VISUAL OUTCOMES, CONTRAST SENSITIVITY, AND SATISFACTION WITH MULTIFOCAL INTRAOCULAR LENS BLENDED TECHNIQUE: LATE MID-TERM RESULTS.

PURPOSE: To describe clinical visual outcomes, spectacle independence, and patient satisfaction after cataract surgery with blending implantation of ReSTOR (Alcon laboratories) multifocal intraocular lenses. MATERIAL AND METHODS: A single-arm, non-randomized prospective study assessed patients undergoing cataract surgery with ReSTOR® +2.50 intraocular lens in the dominant eye and +3.00 add in the fellow eye between January 2015 to January 2020. RESULTS: In total, 47 patients (94 eyes) were enrolled, 28 women and 19 men. The average age at surgery time was 64 ±8 years, average postoperative follow-up was 45.4 ±7.0 months, with a minimum of 18.9 months. Postoperative binocular uncorrected distance visual acuity (UDVA) was on average 0.07 logMar (Snellen 20/24), uncorrected binocular intermediate visual acuity at 65 cm was 0.07 logMar (20/24), uncorrected binocular near visual acuity at 40 cm was 0.06 logMar (20/23). Contrast sensitivity under photopic and scotopic conditions, with and without glare, remained at the upper limit of normality. 98% of patients were quite satisfied or very satisfied. 87% did not require glasses for any activities, either at distant vision, nor at near vision. CONCLUSIONS: Cataract surgery with ReSTOR® IOL blended vision showed medium-term satisfactory visual results, achieving spectacle independence and a high level of satisfaction.

Closed-Incision and Surrounding Soft Tissue Negative Pressure Dressings in Post-Mastectomy Pre-Pectoral Direct-to-Implant Breast Reconstruction: A Pilot Study.

Background: Closed-incision and surrounding soft tissue negative pressure therapy (cistNPT) is theorized to decrease infection, reduce tissue edema, and promote healing of the mastectomy skin flap. We report our early experience with this dressing in pre-pectoral direct-to-implant (pDTI) breast reconstruction. Methods: We retrospectively reviewed all patients who underwent post-mastectomy pDTI breast reconstruction with cistNPT between July 2019 and February 2020. All reconstructions utilized smooth round silicone gel implants and human acellular dermal matrix. Results: Thirty-five female patients underwent 58 mastectomies. Mean age and body mass index were 49.9 years and 28.9 kg/m2, respectively. Eleven (31.4%) patients had neoadjuvant chemotherapy. The mean sternal notch-to-nipple distance was 27.0 cm. The median specimen weight was 483 g, while the median implant volume was 495 cc. The mean implant-to-specimen ratio was 1.4 for nipple-sparing, 1.1 for skin-sparing, and 0.7 for skin-reducing mastectomy. Total drain volume was 483.1 cc from each breast. Post-operative complications included seroma (5.2%), peri-incisional necrosis (8.6%), and superficial skin epidermolysis (13.8%). There were no cases of surgical site infection, dehiscence, or hematoma. Rate of return to the operative room was 3.4%. Mean follow-up was 90 days. Conclusions: In our series of pDTI breast reconstructions with cistNPT, no patients experienced hematoma, dehiscence, or infection complications. Rates of seroma, skin necrosis requiring operative debridement, and total drain volumes were lower than those reported in literature.

Contexte: La thérapie par pression négative des incisions fermées et des tissus mous environnants (cistNPT) doit théoriquement diminuer l'infection, réduire l'œdème tissulaire et faciliter la guérison du lambeau cutané de mastectomie. Nous fournissons notre première expérience avec ce pansement de reconstruction mammaire prépectorale directe à l'implant (pDTI). Méthodes: Nous avons revu rétrospectivement toutes les patientes ayant subi une reconstruction mammaire pDTI post mastectomie entre juillet 2019 et février 2020. Toutes les reconstructions ont utilisé des implants en gel de silicone lisses et ronds avec une matrice dermique acellulaire humaine. Résultats: Trente-cinq femmes ont subi 58 mastectomies. L'âge moyen était de 49,9 ans et l'IMC moyen de 28,9 kg/m2. Onze patientes (31,4 %) recevaient une chimiothérapie néoadjuvante. La distance moyenne du sommet du manubrium sternal au mamelon était de 27,0 cm. Le poids médian de l'échantillon était de 483 g tandis que le volume médian de l'implant était de 495 cc. Le rapport moyen implant/échantillon était de 1,4 pour la préservation du mamelon, 1,1 pour la préservation de la peau et de 0,7 pour la mastectomie de réduction cutanée. Le volume total de drainage de chaque sein a été de 483,1 cc. Les complications postopératoires ont été, notamment, un sérome (5,2 %), une nécrose péri-incision (8,6 %) et une épidermolyse superficielle de la peau (13,8 %). Il n'y a pas eu de cas d'infection du site chirurgical, de déhiscence ou d'hématome. Le taux de reprise chirurgicale a été de 3,4 %. Le suivi moyen a été de 90 jours. Conclusions: Dans notre série de reconstructions du sein par pDTI, aucune patiente n'a eu d'hématome, de déhiscence ou de complication infectieuse. Les taux de sérome, de nécrose cutanée nécessitant un débridement chirurgical et les volumes totaux de drainage étaient inférieurs aux chiffres publiés.

Evaluating Refractive and Visual Outcomes After Bilateral Implantation of an Apodized Diffractive Multifocal Toric Intraocular Lens with a Moderate Add in the Dominant Eye and a Higher Add in the Fellow Eye.

PURPOSE: To review refractive, visual acuity, defocus curve and subjective visual quality results after bilateral implantation of an apodized diffractive toric intraocular lens (IOL) with a moderate add in the dominant eye and a higher add in the non-dominant eye. SETTING: One site in Gainesville, GA, USA. DESIGN: Single arm, non-randomized prospective study. METHODS: This was a single-arm prospective study of visual acuity and subjective visual quality after implantation of a toric low-add apodized diffractive multifocal IOL in the dominant eye and a higher add IOL of the same type in the non-dominant eye three months after surgery. Binocular visual acuity at 4 m, 60 cm and 40 cm was tested. Other tests included refraction, defocus curve measurement and evaluation of the quality of vision. Toric IOL orientation was also measured. RESULTS: A total of 29 subjects were enrolled. There were no statistically significant differences in the mean keratometry, corneal astigmatism or IOL sphere power implanted in the dominant and non-dominant eyes. Vision was preferred without any correction in more than half of the eyes tested (32/58, 55%). The residual refractive astigmatism was ≤ 0.50 D in 100% of eyes. Seventy-five percent of subjects (22/29) had 0.10 logMAR (20/25 Snellen) binocular uncorrected visual acuity at all tested distances. Glare and haloes were the most common visual disturbances, but most subjects (22/29, 76%) reported that they were not bothered by any visual disturbances. In 97% of eyes (56/58), the measured difference in orientation between 1 month and 3 months was less than 5 degrees, with no change more than 14 degrees. CONCLUSION: This blended bifocal IOL modality appears to be well-tolerated by subjects with a good range of vision and minimal bother from visual disturbances.

Visual Outcomes, Visual Quality and Patient Satisfaction: Comparing a Blended Bifocal Approach to Bilateral Extended Depth of Focus Intraocular Lens Implantation.

PURPOSE: To compare visual outcomes, quality of vision and patient satisfaction between a blended apodized diffractive bifocal lens combination and bilateral implantation of an extended depth of focus intraocular lens (IOL). PATIENTS AND METHODS: Subjects implanted with either the blended bifocal (Blended) or bilateral extended depth of focus (EDOF) IOL combinations were examined 3 to 24 months after second eye surgery. The primary outcome measure was the patient's best distance-corrected near visual acuity (VA) at 40cm. The secondary outcome measures were scores on the Quality of Vision Survey, the Catquest-9SF and the Visual Functioning Questionnaires, uncorrected binocular intermediate and near VA at 4-6m, 60cm and 40cm, the manifest refraction and the best-corrected monocular and binocular distance VA. RESULTS: Twenty-five EDOF subjects and 23 blended subjects were analyzed. The uncorrected and best-distance corrected intermediate VA was statistically significantly better in the EDOF group (p < 0.05); no other significant differences were noted at distance or near. The EDOF group had significantly higher percentage of patients having no difficulty with hobbies and handicrafts (p < 0.05). Eighty-seven percent of the blended subjects and 79% of the EDOF subjects were "very" or "fairly" satisfied with their vision (p = 0.52). The frequency, severity and degree of bother from visual disturbances were comparable between the two groups; however, more subjects in the EDOF group reported severe disturbances (36% vs 4%). CONCLUSION: Distance and near VA are similar with both IOL designs, but intermediate VA was better with the EDOF IOL resulting in lower difficulty with intermediate tasks such as hobbies and handicrafts. Despite the difference at intermediate VA, satisfaction was similar between the two groups and there were greater reports of severe visual disturbances in the EDOF group.

Comparison of visual quality in cataract patients with low astigmatism after ART2 or ReSTOR intraocular lens implantation.

AIM: To compare visual quality in cataract patients with low corneal astigmatism who underwent intraocular lens (IOL) implantation, and evaluate effects of low levels of astigmatism on visual outcomes in multifocal pseudophakic eyes. METHODS: This retrospective review of clinical records comprised patients with preoperative regular corneal astigmatism of 0.75-1.0 diopters (D) with-the-rule or 0.5-0.75 D against-the-rule who had uneventful cataract surgery and AcrySof IQ ReSTOR Toric-2 IOL (ART2) or AcrySof IQ ReSTOR IOL (ReSTOR) implantation. Retrospective data collection included postoperative ART2 axis rotation, uncorrected astigmatism, uncorrected entire visual acuities, distance corrected entire visual acuities, average modulation transfer function (aMTF), Strehl ratio (SR), spectacle independence, and patient satisfaction between groups. RESULTS: Mean ART2 axis rotation was 3.12°±0.70°. No secondary surgery was required to realign IOL axis. Residual astigmatism values were -0.18±0.07 D and -0.91±0.25 D in groups ART2 and ReSTOR (P<0.05). Three months postoperatively, the mean uncorrected distant, intermediate, and near visual acuities of group A were 0.01±0.05, 0.05±0.07, 0.02±0.07 logMAR, respectively; these were better than those of group R, which were 0.08±0.06, 0.15±0.12, and 0.09±0.08 logMAR, respectively (P<0.05). aMTF, SR, and spectacle independence rates were not significantly different. All patients were satisfied with postoperative results. CONCLUSION: ART2 is more suitable than ReSTOR for cataract patients with regular corneal astigmatism 0.75-1.0 D with-the-rule or 0.5-0.75 D against-the-rule.

Patient-Reported Outcomes/Satisfaction and Spectacle Independence with Blended or Bilateral Multifocal Intraocular Lenses in Cataract Surgery.

PURPOSE: To compare patient-reported outcomes (PROs) and satisfaction results after multifocal intraocular lens (IOL) implantation in three groups: two receiving bilateral implantation of the same IOL and another undergoing blended vision with two different multifocal IOLs. PATIENTS AND METHODS: A questionnaire was administered to patients who had undergone uncomplicated cataract surgery and 2 months of follow-up: the first group underwent bilateral implantation with Alcon's AcrySof ReSTOR 3.0 lens ("3.0/3.0," n=78); the second group underwent implantation with the ReSTOR ActiveFocus 2.5 or the ReSTOR ActiveFocus 2.5 toric lens ("2.5 mini-monovision," n=102); and the third group underwent implantation with the ReSTOR 2.5 lens in the dominant eye and the ReSTOR 3.0 lens in the non-dominant eye ("2.5/3.0," n=89). RESULTS: Overall PROs and satisfaction was similar among the groups. Refractive outcomes and accuracy were similar among the groups, but the 2.5 mini-monovision group reported better intermediate vision. Refractive outcome differences were not meaningful among the groups and were not a differentiating factor in PROs. Substantially fewer patients in the 2.5 mini-monovision group noticed glare and halo compared with the 3.0/3.0 group (P<0.0001, chi-square test). No new safety concerns were reported. CONCLUSION: The 2.5 mini-monovision results in a higher percentage of patients being satisfied with intermediate vision than bilateral ReSTOR 3.0 or blended vision with ReSTOR 2.5/3.0 implants, but overall PRO differences were not statistically significant.

Unilateral Multifocal Intraocular Lens Implantation in a Patient with Adie's Pupil.

PURPOSE: To report a case of a patient with unilateral Adie's pupil who underwent bilateral cataract extraction with multifocal and monofocal posterior chamber intraocular lens (IOL) implantation. METHODS: A 74-year-old woman presented to our institution complaining of worsening near vision. Gross examination revealed a 6-mm fixed pupil on the right eye (OD) and a 5-mm pupil reacting to 3 mm with light on the left eye (OS). Slit lamp examination revealed a tonic pupil with an exaggerated pupillary constriction to dilute pilocarpine OD. Dilated exam revealed 2-3+ nuclear and cortical lens changes bilaterally. The patient's active lifestyle, personality, and biometry measurements made her a good candidate for multifocal IOL (MfIOL) implantation OS. Femtosecond laser-assisted cataract extraction with a ReSTOR +3 ADD (SN60D1) implantation was performed OS. Monofocal lens implantation (SN60WF) was performed OD 6 months later. RESULTS: One year postoperatively, our patient had an uncorrected visual acuity (VAsc) of 20/15 for distance and J10 for near OD. Her VAsc was 20/25 +1 for distance and J1 for near OS. Visual acuity when using both eyes was 20/15 for distance and J1 for near. CONCLUSION: Optimizing success for MfIOL implantation is a multifactorial process. Large pupils preoperatively are of particular concern, as this may lead to increased dysphotopsia with pupil-dependent MfIOLs. Thus, patients with unilateral mydriasis, such as Aide's pupil, may have a beneficial outcome combining multifocal-monofocal implantation after bilateral cataract extraction, especially if they are not a candidate for monovision but desire spectacle independence.

Patient-reported outcomes of multifocal and accommodating intraocular lenses: analysis of 117 patients 2-10 years after surgery.

PURPOSE: The purpose of this study was to determine the satisfaction levels of patients at least 2 years after cataract surgery implantation with bilateral accommodating or bilateral multifocal intraocular lenses (IOLs) and to determine the relative rate of spectacle independence and adverse symptoms in that same time frame. DESIGN: Patient questionnaire administered in a single-center private practice at least 2 years after cataract surgery with presbyopia-correcting IOL implantation. METHODS: Patients who had undergone uncomplicated cataract surgery with an accommodating or multifocal IOL implant were eligible for inclusion. Patients with visually significant non-IOL-related postoperative morbidity were excluded. Patients with astigmatism or residual refractive error were not excluded. The main outcome measure was patient satisfaction at least 2 years after IOL implantation. RESULTS: Sixty-eight patients who received accommodating lenses and 49 patients who received multifocal lenses completed the questionnaire. The mean age of all patients was 75.7 years at the time of survey; the mean number of years since cataract surgery was 5.4 years. Overall, there were no significant differences between the two groups or within each group between the different lenses used. About 90% of patients in each group were "very satisfied" or "somewhat satisfied" with their vision at least 2 years after the initial surgery. Conversely, only one in eleven patients found his vision to be worse than expected. CONCLUSIONS: The majority of patients who received either accommodating or multifocal IOLs remain satisfied with their lens of choice more than 5 years after the original surgery. Glare and halos remain more noticeable in patients who received multifocal lenses.

Bilateral implantation of +3.0 D multifocal toric intraocular lenses: results of a US Food and Drug Administration clinical trial.

PURPOSE: The purpose of this study was to evaluate the clinical outcomes of apodized diffractive +3.0 D multifocal toric intraocular lens (IOL) implantations in subjects with preoperative corneal astigmatism. PATIENTS AND METHODS: This was a prospective cohort study conducted at 21 US sites. The study population consisted of 574 subjects, aged ≥21 years, with preoperative astigmatism 0.75-2.82 D, and potential postoperative visual acuity (VA) ≥0.2 logMAR, undergoing bilateral cataract removal by phacoemulsification. The intervention was bilateral implantation of aspheric apodized diffractive +3.0 D multifocal toric or spherical multifocal nontoric IOLs. The main outcome measures were monocular uncorrected near and distance VA and safety at 12 months. RESULTS: A total of 373/386 and 182/188 subjects implanted with multifocal toric and nontoric IOLs, respectively, completed 12-month follow-up after the second implantation. Toric IOLs were nonin-ferior in monocular uncorrected distance (4 m) and near (40 cm) VA but had >1 line better binocular uncorrected intermediate VA (50, 60, and 70 cm) than nontoric IOLs. Toric IOLs reduced cylinder to within 0.50 D and 1.0 D of target in 278 (74.5%) and 351 (94.1%) subjects, respectively. Mean ± standard deviation (SD) differences between intended and achieved axis orientation in the first and second implanted eyes were 5.0°±6.1° and 4.7°±4.0°, respectively. Mean ± SD 12-month IOL rotations in the first and second implanted eyes were 2.7°±5.8° and 2.2°±2.7°, respectively. No subject receiving toric IOLs required secondary surgical intervention due to optical lens properties. CONCLUSION: Multifocal toric IOLs were noninferior to multifocal nontoric IOLs in uncorrected distance and near VAs in subjects with preexisting corneal astigmatism and effectively corrected astigmatism of 0.75-2.82 D.

Comparison of visual outcomes after implantation of diffractive trifocal toric intraocular lens and a diffractive apodized bifocal toric intraocular lens.

PURPOSE: The aim of this study was to compare a new diffractive trifocal toric lens with an apodized diffractive bifocal toric lens in terms of refractive and visual acuity (VA) outcomes, including low-contrast VA (LCVA), as well as the patient's visual function 3 months after implantation. PATIENTS AND METHODS: This is a randomized prospective study involving bilateral implantation of a trifocal toric or a bifocal toric lens. At 3 months postoperatively, the subject's vision was tested both uncorrected and with his/her best distance correction at: distance (4 m), intermediate (63 cm), and near (40 cm). Binocular defocus curves were measured with no correction and with the subject's best distance correction in place. Quality of vision was measured using the National Eye Institute Visual Function Questionnaire. RESULTS: A total of 22 patients were enrolled (eleven in each group). There was no statistically significant difference in the absolute change in measured rotation between 1 month and 3 months postoperatively between the two intraocular lens (IOL) groups (P=0.98). At 3 months, the postoperative refraction and distance VA by eye were similar between groups. There was no statistically significant difference in the measured LCVA between groups (P=0.39). The defocus curve showed that at 67 cm, the trifocal toric lens had statistically significantly better VA when compared to the bifocal toric lens. There were no statistically significant differences by group for any of the National Eye Institute Visual Function Questionnaire scores (P>0.26 in all cases). CONCLUSION: The trifocal toric IOL improved the intermediate vision without negatively impacting visual function and distance, near, or low-contrast VA when compared to a bifocal toric IOL. The toric component of the trifocal lens effectively reduced astigmatism and provided good rotational stability.

Comparison of visual outcomes and subjective visual quality after bilateral implantation of a diffractive trifocal intraocular lens and blended implantation of apodized diffractive bifocal intraocular lenses.

PURPOSE: To compare the visual acuity (VA) and quality of vision between bilateral implantation of a trifocal intraocular lens (IOL) and blended bifocal IOLs with an intermediate add in the dominant eye and a near add in the nondominant eye. PATIENTS AND METHODS: Patients with either trifocal or blended bifocal IOLs implanted were recruited after surgery. Subjects returned for a single diagnostic visit between 3 and 24 months after surgery. VA was tested at various distances, including low-contrast acuity and acuity at their preferred reading distance. A binocular defocus curve was obtained, and subjective visual function and quality of vision were evaluated. RESULTS: Twenty-five trifocal subjects and 30 blended bifocal subjects were enrolled. There were no significant differences in low-contrast acuity, preferred reading distance, or acuity at that reading distance. Binocular vision at 4 m, 60 cm, and 40 cm was not statistically significantly different. The trifocal provided statistically significantly better visual acuity (P<0.05) at vergences from -0.5 to -1.5 D (from 2 m to 67 cm viewing distance, P<0.05). There was no statistically significant difference in the near vision subscale scores of the 39-question National Eye Institute Visual Function Questionnaire or the overall scores of the Quality of Vision questionnaire, though significantly more trifocal subjects reported that the observed visual disturbances were "bothersome" (P<0.05). CONCLUSION: Both lens modalities provided subjects with excellent binocular near and distance vision, with similar low rates of visual disturbances and good reported functional vision. The trifocal IOL provided significantly better intermediate VA in the viewing distance range of 2 m to 67 cm, corresponding to viewing things such as a car dashboard or grocery shelf. VA was similar between groups at viewing distances from 60 to 40 cm, corresponding to computer or reading distance.

Multifocal Toric Intraocular Lens for Traumatic Cataract in a Child.

A child suffering from traumatic cataract and corneal astigmatism of 2.14 D had a phacoemulsification operation and implantation of a ReSTOR Toric intraocular lens (IOL) to correct the astigmatism. The primary outcome measurements were the uncorrected distance visual acuity (UDVA), uncorrected near vision at 40 cm, intraocular pressure, spherical equivalent refraction, residual astigmatism, corneal astigmatism, presence of unusual optical phenomena, and use of spectacles. At 7 months postoperatively, UDVA was maintained between 16/20 and 24/20, near vision was between J1 and J3, residual spherical refraction was 0-0.37 D, and residual refractive cylinder was between 0 and 0.67 D. A multifocal toric IOL can provide the possibility of satisfactory vision for both distant and near conditions without the use of spectacles to meet children's needs when studying and doing sports. Additionally, binocular vision can be reconstructed. This intervention, therefore, seems to be a satisfactory alternative.

Tratamento expectante, tratamento expectante modificado e técnica ART: indicações, contraindicações, técnicas e relevância clínica / Expectant treatment, modified expectant treatment, and ART technique: indications, contraindications, techniques, and clinical relevance

Introdução: A doença cárie possui uma etiologia multifatorial que pode atingir toda a estrutura dentária. Em cavidades profundas, o tratamento expectante pode ser realizado com a finalidade de evitar danos à polpa. Já em lesões iniciais, a técnica ART é uma alternativa aceitável para o caso. Objetivo: Discutir sobre as indicações, contraindicações, técnicas e relevâncias clínicas do tratamento expectante (convencional e modificado) e da técnica restauradora atraumática (ART) no tratamento das lesões cariosas. Métodos: Foi realizada uma revisão da literatura de artigos científicos publicados nas bases de dados PubMED/Medline e Scielo, entre 2009 e 2020, e de livros considerados relevantes para este estudo. Resultados: No tratamento expectante, a remoção da dentina cariada é realizada em duas etapas: remoção da lesão cariosa de forma superficial, na primeira consulta, e remoção final após diferentes intervalos de tempo. No entanto, alguns autores defendem que não é necessária a realização da segunda etapa, basta apenas rebaixar o cimento de ionômero de vidro restaurador e, em seguida, realizar a restauração definitiva, técnica nomeada como tratamento expectante modificado. Com relação à técnica ART, o manejo da lesão é feito com a mínima intervenção possível, utilizando apenas instrumentos manuais. É confiável e bem aceita, principalmente na clínica de Odontopediatria. Ambas culminam em resultados terapêuticos favoráveis. Conclusão: Inicialmente, o dentista deve sempre realizar um diagnóstico minucioso das lesões de cárie, visando a máxima prevenção da estrutura dental. Devemos optar pelo tratamento restaurador convencional somente quando outros métodos não forem mais suficientes para interromper a progressão da lesão.

Introduction: Caries disease has a multifactorial etiology and can affect the entire tooth structure. In deep cavities, expectant treatment can avoid damage to the pulp. In early lesions, the ART technique is an acceptable alternative. Objective: To discuss indications, contraindications, techniques, and clinical relevance of the expectant treatment (conven-tional and modified) and the ART technique in the treatment of carious lesions. Methods: A literature review of scientific articles (published in PubMED/Medline and Scielo data-bases, between 2009 and 2020) and books considered relevant to this study. Results: In the expectant treatment, carious dentin is removed in two stages: a superficial removal of the carious lesion at the first visit, and a final removal after different time intervals. However, some authors argue that it is not necessary to perform the second step. Just lower the glass-ionomer cements and then perform the definitive restoration, a technique known as modified expectant treatment, is necessary. Regarding the ART technique, the management of the lesion is conducted with the least possible intervention, using only manual instruments. It is reliable and well accepted especially in the Pediatric Dentistry clinic. Both culminate in favorable therapeutic results. Conclusion: Initially, the dentist must always carry out a thorough diagnosis of caries lesions aiming at the maximum prevention of the dental structure. You should opt for conventional restorative treatment only when other methods are no longer sufficient to stop the progression of the lesion.

Spectacle Independence after Cataract Extraction in Post-Radial Keratotomy Patients Using Hybrid Monovision with ReSTOR(®) Multifocal and TECNIS(®) Monofocal Intraocular Lenses.

BACKGROUND: We report 2 patients who have undergone radial keratotomy (RK) preceding ReSTOR(®) multifocal intraocular lens (IOL; Alcon, Fort Worth, Tex., USA) implantation in their nondominant eyes and TECNIS(®) monofocal IOL (Abbott Medical Optics, Abbott Park, Ill., USA) in their dominant eyes. METHODS: Retrospective review of 2 patients who underwent hybrid monovision with ReSTOR(®) multifocal and TECHNIS(®) monofocal IOLs at the time of cataract surgery after a remote history of RK. RESULTS: Implantation of the ReSTOR(®) multifocal and the TECHNIS(®) monofocal IOLs was successful, with no reported adverse events. The patients were able to achieve spectacle freedom. CONCLUSION: We report a novel technique for the management of post-RK patients to optimize their chances for spectacle independence.

AIM: By comparing the aspheric and multifocal Toric intraocular lens and the aspheric intraocular lens in cataract patients,to observe the patients` visual quality,to evaluate the patients` distance visual acuity,near visual acuity,Pseudo-accommodative power,residual astigmatism,the rotational stability of AcrySof IQ Toric Restor intraocular lens (IOLs),contrast the rate of off-distance glass,the rate of off-near glass and patient satisfaction after the implantation of AcrySof IQ Toric Restor IOL in the cataract patients with preexisting corneal astigmatism.METHODS:Carried out in 46 patients (48 eyes) with age-rated cataract who receiving phacoemulsification and implantation of artificial lens in our department during February 2014 to June 2016.All the cases were randomly divided into 2 groups: experimental group: 23 cases (24 eyes),AcrySof IQ ReSTOR Toric IOL was implanted after phacoemulsification;control group: 23 cases (24 eyes),AcrySof IQ was implanted.Uncorrected distance visual acuity (UCDVA) and best corrected distance visual acuity (BCDVA),uncorrected near visual acuity (UCNVA) and best-corrected near visual acuity(BCNVA),Pseudo-accommodative power,residual astigmatism,preoperative and postoperative corneal astigmatism,the rate of off-distance glass,the rate of off-near glass and patient satisfaction were measured at 6mo postoperatively follow-up.RESULTS: BCDVA and BCNVA were not statistically different between the two groups(P<0.05).At 1wk,1,3 and 6mo postoperatively of UCDVA the experimental group were statistically better than the control group (P<0.05).UCNVA were also statistically better than the control group (P<0.05).The mean residual astigmatisms 1wk,1,3 and 6mo postoperatively were statistically differences between the control group and experimental group (P<0.05).At 6mo postoperatively,patients satisfaction of experimental group were significantly better than control group (P<0.05).Spectacles independence for near vision achieved 83% and 17% in experimental group and control group,experimental group were statistically better than control group(P<0.05).Spectacles independence for distance vision achieved 92% and 67% in experimental group and control group,experimental group were statistically better than control group(P<0.05).CONCLUSION:The results indicate that AcrySof IQ ReSTOR Toric IOLs may provide a better uncorrected distance visual acuity and uncorrected near visual acuity,which can significantly reduce preexisting corneal astigmatism in cataract surgery,improve spectacles independence for distance vision and spectacles independence for near vision,have a high patient satisfaction.

Early clinical effects of phacoemulsification cataract surgery with implantation of Acrysof IQ Restor multi-focal toric lens / 医学研究生学报

Objective Acrysof IQ Restor multifocal toric intraocular lens ( IOL) is a new product , which allows a single sur-gical procedure for presbyopia correction and corneal astigmatism management .This study was to evaluate the early clinical effects of phacoemulsification cataract surgery with implantation of a diffractive multifocal toric IOL . Methods We retrospectively analyzed 7 cases (9 eyes) of corneal astigmatism ≥1.0 diopter (D) treated by phacoemulsification with implantation of an Acrysof IQ Restor toric IOL.The patients were followed up for 3 months for observation of uncorrected distance visual acuity ( UDVA) , best corrected distance visual acuity ( CDVA) , uncorrected near visual acuity ( UNVA ) , best corrected near visual acuity ( CNVA ) , spherical equivalent (SE) refraction, focal depth, residual astigmatism, rotational stability of the IOL, contrast sensitivity (CS), and spectacle independ-ence preoperatively and at 1 week, 1 month, and 3 months after operation . Results At 3 months after surgery , the UDVA ( log-MAR), CDVA, UNVA, and CNVA were 0.07 ±0.10, 0.02 ±0.11, 0.12 ±0.06, and 0.08 ±0.07, respectively, with an SE re-fraction within ±0.50 D of the attempted spherical correction in 8 eyes (88.9%) and a focal depth of (5.32 ±1.78) D.The residual astigmatism at 3 months was significantly reduced as compared with the baseline ([0.25 ±0.28] vs [1.55 ±0.39] D, P0.05).At 3 months, the mean IOL axis rotation was (3.11 ±1.61)°and CS was remarkably im-proved ( P0.05) except at 18.0 cpd (P<0.05). Conclusion Implantation of the Acrysof IQ Restor multifocal toric IOL provides excellent overall quality of vision, spectacle independence, visual quality, and rotational stability for patients with cataract and corneal astigmatism.

Visual Outcome and Patient Satisfaction after Implantation of Multifocal IOLs: Three-Month Follow-Up Results

PURPOSE: To evaluate the visual outcome and patient satisfaction at three months after implantation of ReSTOR(R) Aspheric multifocal IOL D1 (+3.0 D) and D3 (+4.0 D) in unilateral and bilateral cataract surgery groups. METHODS: Among 73 patients who received cataract surgery and implantation of D1 or D3, visual outcome and satisfaction score of 34 patients in the unilateral surgery group and 39 patients in the bilateral surgery group were analyzed respectively. The unilateral surgery group was divided into 2 sub-groups (D1, D3), and the bilateral surgery group was sub-divided into 3 groups (D1/D1, D1/D3, D3/D3) according to the combination of implanted IOL. Uncorrected near visual acuity (UNVA, 30 cm), uncorrected intermediate visual acuity (UIVA, 40 cm, 50 cm), uncorrected distant visual acuity (UDVA) and best corrected visual acuity (BDVA) were measured at three months postoperatively. Also, all patients answered questionnaires to assess satisfaction. RESULTS: In the unilateral surgery sub-groups, visual acuity of the D1 group was higher than that of the D3 group at 50 cm (p < 0.001), although the D3 group showed better visual outcome at 30 cm (p < 0.001). In satisfaction analysis, the D1 group reported significantly higher scores in three categories (general satisfaction with surgery; p = 0.027, intermediate vision; p < 0.001, recommendation to others; p = 0.026). Among the bilateral surgery groups, the D1/D1 group showed the best intermediate visual acuity at 50 cm (p = 0.011), and the D3/D3 group achieved the highest postoperative near visual acuity (p = 0.004). In satisfaction analysis, the scores of the three categories (general satisfaction with surgery; p = 0.008, intermediate vision; p < 0.001, recommendation to others; p = 0.006) showed significant differences among the three groups, with the D1/D1 group reporting the highest scores in all three categories. CONCLUSIONS: In bilateral ReSTOR(R) lens implantation, insertion of D1 in both eyes is expected to achieve the most favorable visual outcome and patient satisfaction. In unilateral ReSTOR(R) lens implantation, implantation of D1 rather than D3 would be more advantageous in general.

The Effects of Laser Refractive Surgery for Correcting Residual Refractive Error after Implantation of ReSTOR(R) Multifocal IOL

PURPOSE: To evaluate the clinical effects of excimer laser refractive surgery on eyes with residual refractive error after implantation of ReSTOR(R) multifocal intraocular lenses. METHODS: We retrospectively reviewed the medical records of 10 eyes of 6 patients who had undergone cataract surgery with implantation of multifocal intraocular lenses. Photorefractive keratectomy (PRK) (5 eyes) and laser-assisted in situ keratomileusis (LASIK) (5 eyes) was performed on 10 eyes with residual refractive error. RESULTS: After cataract surgery and before laser surgery, the mean spherical equivalent (SE) was -0.34 +/- 0.89 D and the mean astigmatism was 2.08 +/- 0.55 D. Six months after laser surgery, the mean SE was -0.33 +/- 0.30 D (p = 0.354) and the mean astigmatism was 0.23 +/- 0.28 D. The changes in astigmatism between paired preoperative and postoperative values were statistically significant (p < 0.0001). At 6 months after surgery, uncorrected distance visual acuity significantly improved to 0.11 +/- 0.10 (log MAR) (p < 0.0001) There were no significant changes in the best corrected distance visual acuity and uncorrected near visual acuity (p = 0.073, p = 0.100). CONCLUSIONS: On the basis of predictability and stability, excimer laser surgery appears to be a clinically useful procedure to correct residual refractive error after implantation of ReSTOR(R) multifocal intraocular lenses.
