RESUMO
BACKGROUND: This study compared topical anesthesia to a combination of topical anesthesia and subconjunctival anesthesia for phacoemulsification. METHODS: This double-blinded parallel placebo-controlled randomized trial involved senile cataract patients scheduled for phacoemulsification between May and December 2022. Patients were randomly assigned to receive either topical anesthesia with 0.5% tetracaine hydrochloride and subconjunctival balanced salt solution injection (Control group) or topical anesthesia and subconjunctival injection with 2% lidocaine (Lidocaine group). Baseline parameters, cataract grades, and various outcomes were recorded, including pain scores at specific time points, patient cooperation scores, requests for additional anesthesia, and complications. Statistical methods included Fisher's exact test, the t-test, ordinal logistic regression, and linear regression with robust standard errors. RESULTS: In total, 176 patients were included in the study after excluding 33 patients. A significant reduction in immediate postoperative pain was achieved in the Lidocaine group (p < 0.001) and was maintained for 2 h (p = 0.011). Additionally, better cooperation was observed in this group (p = 0.038). However, patients in the Lidocaine group experienced more pain during the subconjunctival injection (p = 0.001) and a significant increase in subconjunctival hemorrhage related to the injection (p < 0.001). Despite this, the rates of surgical complications were comparable between the groups, and all phacoemulsification procedures were successfully completed using the assigned anesthetic technique. CONCLUSIONS: The addition of subconjunctival lidocaine injection to topical anesthesia reduced postoperative pain and improved patient cooperation during phacoemulsification. However, the lidocaine injection was painful, and it carried a higher risk of spontaneous-relief subconjunctival hemorrhage. TRIAL REGISTRATION: Trial Registration Number: TCTR20220804003, date of registration August 4, 2022, retrospectively registered.

PURPOSE: To compare posterior chamber phakic intraocular lens (Implantable Collamer Lens [STAAR Surgical]) (ICL) plus modified steep meridian corneal relaxing incision (MS-CRI) to toric posterior chamber phakic intraocular lens (Toric Implantable Collamer Lens [STAAR Surgical]) (TICL) implantation for the correction of moderate to high astigmatism. METHODS: In this prospective, randomized clinical trial, patients with myopia who had moderate to high astigmatism (200 eyes) were enrolled and divided into TICL (n = 100) and MSCRI (n = 100) groups. All patients underwent examinations for uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and subjective refraction before surgery and at the 1- and 6-month follow-up visits. Vector astigmatism analysis was evaluated using the Alpins method. RESULTS: The mean UDVA and CDVA demonstrated significant improvement after surgery in both groups. During the 6-month follow-up, the MS-CRI group showed a slight regression tendency (P < .001) and the TICL group was stable for the astigmatism correction (P = .510). At 6 months postoperatively, the mean magnitudes of the surgically induced astigmatism were 1.46 ± 0.53 and 1.10 ± 0.48 diopters (P < .001). The correction index of the TICL group was closer to 1 compared to that of the MS-CRI group (0.95 vs 0.76). Approximately 99% of eyes in the TICL group had angle of error within ±15°, whereas 89% eyes in the MS-CRI group were within that range. A significant relationship between the magnitudes of target induced astigmatism and correction index was noted in the MS-CRI group (P < .001), but not in the TICL group (P = .592). CONCLUSIONS: TICL implantation could achieve better visual outcomes for correcting moderate to high astigmatism compared to ICL implantation plus MS-CRI. [J Refract Surg. 2023;39(8):539-545.].

BACKGROUND: This prospective comparative study aimed to investigate the influence of diffractive trifocal intraocular lenses (IOLs) implantation on standard automated perimetry. METHODS: Patients with no diseases affecting the visual field had undergone cataract surgery following the implantation of trifocal or monofocal IOLs from July 2019 to August 2020 were recruited. The normality of the anterior and posterior segments and absence of glaucomatous optic nerve cupping were confirmed preoperatively by slit-lamp examination. Standard automated perimetry was performed using Humphrey Visual Field 10-2 testing, 2-3 months after cataract surgery in only one eye per patient. The mean deviation (MD) and foveal sensitivity were compared between IOLs in eyes with acceptable reliability indices and best-corrected visual acuity of 20/25 or better. RESULTS: Among the 83 eyes of the 83 patients included, 39 and 29 eyes eligible for perimetry analysis had trifocal and monofocal IOLs, respectively. The mean MD and foveal sensitivity in eyes with trifocal IOLs were significantly lower than those in eyes with monofocal IOLs (P < 0.021), with mean differences of 0.77 and 1.01 dB, respectively. CONCLUSION: The comparison in nonglaucomatous eyes demonstrated that the influence of trifocal IOLs on standard automated perimetry was greater than that of monofocal IOLs.

BACKGROUND: This study aimed to compare surgically induced astigmatism (SIA) on the anterior and total cornea during cataract surgery through a 2.2 mm steep meridian incision. METHODS: The study included 69 left eyes of 69 patients who had undergone cataract surgery. The 69 eyes were classified into three subgroups according to the preoperative steep meridian. Following phacoemulsification, an intraocular lens was inserted into the bag. The keratometric measurements were taken 12 months postoperatively, on the anterior cornea (automated keratometer and anterior keratometry [K] from a rotating Scheimpflug camera) and total cornea (equivalent K reading [EKR] 3.0 mm, EKR 4.5 mm, total corneal refractive power (TCRP) 2.0 mm ring, TCRP 3.0 mm zone, TCRP 4.0 mm zone). The SIA was analyzed for each parameter. RESULTS: On the double-angle polar plot, the summated vector mean values of SIA determined by the automated keratometer and Scheimpflug anterior K were 0.28 diopter (axis: 177°) and 0.37 diopter (axis: 175°) in with-the-rule (WTR) astigmatism; 0.03 diopter (axis: 156°) and 0.18 diopter (axis: 177°) in oblique astigmatism; 0.15 diopter (axis: 96°) and 0.17 diopter (axis: 73°) in against-the-rule (ATR) astigmatism. The mean SIAs on the total cornea ranged from 0.31 to 0.42 diopter in WTR astigmatism; from 0.16 to 0.27 diopter in oblique astigmatism; from 0.04 to 0.11 diopter in ATR astigmatism. Mean magnitude SIA ranged from 0.41 to 0.46 diopter on anterior corneal surface and 0.50 to 0.62 diopter on total cornea. J0 and J45 of the posterior cornea showed no significant changes after cataract surgery, and the changes in J0 and J45 did not show any statistical differences between the anterior and total cornea (all p > 0.05). CONCLUSIONS: There were no differences in the summed vector mean values of SIA between the anterior cornea and the total cornea.

PURPOSE: To evaluate the relationship between the incidence of complications and functionally monocular patients' emotional reactions during phacoemulsification under topical anesthesia. METHODS: We enrolled 22 functionally monocular patients (11 males and 11 females; group 1) and 19 age- and sex-matched controls (6 males and 13 females; group 2) in this prospective, interventional, cross-sectional, case control study. Demographics data, including age, sex, and educational background, were collected. Surgeries were performed by the same surgeon, and during surgery, the patients' vital signs (blood pressure and heart rate) and surgical events (duration, body movements, signs of increased vitreous cavity pressure, difficulty in performing capsulorhexis, and complications) were noted. Pre- and postoperative visual acuity was also analyzed. RESULTS: The mean age of group 1 was 73.05 ± 13.31 years and of group 1 was 69.74 ± 16.81 years. There was no significant between-group difference in systolic and diastolic blood pressures. The average heart rate was similar in both groups, too. During surgery, the surgeon's perception of excessive eye, eyelid, or head movements in both groups was similar, in addition to signs of increased vitreous cavity pressure. CONCLUSION: It is safe to perform phacoemulsification under topical anesthesia in functionally monocular patients, who apparently behave similarly to binocular patients.

PURPOSE: To estimate the association of cefuroxime and moxifloxacin in relation to the occurrence of endophthalmitis following phacoemulsification cataract surgery. DESIGN: Retrospective clinical cohort study. METHODS: We studied patients with noncomplex phacoemulsification cataract surgery in Kaiser Permanente Northern California during 2014-2019. Data were obtained for acute, postoperative endophthalmitis within 90 days of phacoemulsification, including culture and antibiogram results, intracameral and topical antibiotic agent, and dose. In a post hoc analysis, we also examined preoperative anterior chamber depth (ACD) and postoperative anterior chamber volume (ACV). RESULTS: Of 216,141 surgeries, endophthalmitis occurred in 0.020% of moxifloxacin-injected eyes and 0.013% of cefuroxime eyes (relative risk 1.62 with 95% CI 0.82-3.20, P = .16). Of the 34 (0.016%) cases of endophthalmitis, cefuroxime 1 mg was injected into 13 eyes and moxifloxacin 0.1% into 21 eyes. Organisms with antibiograms were identified in 12 (35%) cases. Of these, bacteria recovered from cefuroxime-injected eyes were resistant to cefuroxime in all cases (4/4), with Enterococcus comprising half of these. In eyes injected with moxifloxacin 0.1%, 6 out of 7 organisms were sensitive to moxifloxacin injected with 0.1 mL and in 1 eye injected with 1 mL. Streptococcus was the most common organism recovered (6/9) in moxifloxacin-injected eyes. Preoperative ACD and postoperative calculated ACV were higher in eyes injected with moxifloxacin. CONCLUSIONS: Endophthalmitis cases with positive cultures were generally related to organism resistance in cefuroxime eyes but to sensitive organisms in moxifloxacin eyes. Moxifloxacin doses may have been insufficient in eyes with larger ACV.

PURPOSE: To evaluate the efficacy of topical fresh frozen plasma (FFP) therapy on clinical symptoms, findings, and prognosis after anterior segment surgeries in patients with ligneous conjunctivitis (LC). METHODS: Retrospective case note review. RESULTS: Eleven eyes of 7 cases whose remission was not achieved after medical treatment such as topical corticosteroids, cyclosporine A, and heparin were included in the study. The median age of admission was 19 (1-49) years, median duration of FFP treatment was 48 (15-79) months, median follow-up period was 62 (16-114) months, and median age at symptom onset was 12 (4-252) months. Diagnosis was made according to clinical presentations, plasminogen activities, and response to treatment. Topical FFP that was prepared in our clinic was used in all cases. Surgeries (membrane excision, eyelid surgery, deep anterior lamellar keratoplasty, and cataract surgery) were performed after at least 1 month of FFP treatment. Prosthetic contact lens was applied to one eye. During the follow-up period, recurrences requiring membrane excision and side effects from topical FFP were not observed. CONCLUSIONS: LC is a rare membranous conjunctivitis that proceeds with remissions and recurrences. When it was shown that the etiology of LC is plasminogen deficiency, FFP became the only treatment option targeting the etiology. In this study, we observed that the topical FFP is an effective treatment method that prevents recurrence and ensures regression of membranes and safer anterior segment surgeries in LC.

An innovative intraocular lens (IOL), the CM-T Flex IOL, was used to correct surgical aphakia without disturbing a functioning filtering bleb. A 66-year-old man presented with aphakia in the left eye. Cataract extraction and trabeculectomy was performed in the left eye 2 years previously elsewhere. Corrected distance visual acuity (CDVA) in the left eye was 6/18, and, on examination, it showed a filtering bleb that encroached on the limbus and superior cornea. The cornea was clear with a deep anterior chamber. Retinal examination was normal. Disc cupping was noted with a cup-to-disc ratio of 0.8. Refractive correction was performed by implanting the CM-T Flex IOL. This IOL has a unique design that eliminates the need for maneuvering the IOL haptics extraocularly. It entails a simple grasp, exteriorize, and release technique that anchors the IOL firmly to the scleral bed. At 6 months, CDVA in the left eye was 6/9 with a stable, centered IOL.

RATIONALE: Although intraocular lens (IOL) dislocations have been reported after uneventful cataract surgeries, no sequential changes have ever been demonstrated. Our case showed the sequential changes to IOL dislocation caused by vigorous ocular massage. PATIENT CONCERNS: A 42-year-old man complained of blurred vision in the left eye 8 years after uneventful phacoemulsification. The IOL was still well-centered, but curvilinear tears of the anterior and posterior capsule along the optic border of IOL and vitreous herniation were noted. In the following month, the IOL subluxated inferiorly. A careful history taking revealed a recent habit of vigorous ocular massage. The subluxation was stable for 2 years after avoiding ocular massage, but dislocation into vitreous occurred after taking a spring water bath (spa) bath with massage. DIAGNOSIS: IOL dislocation. INTERVENTIONS: Pars plana vitrectomy to remove the dislocated IOL and implantation of a 3-piece IOL into sulcus were performed. OUTCOMES: The IOL was well-centered. The visual acuity returned to 20/20. LESSONS: Ocular massage might cause tear of the intact fibrotic capsule and dislocation of IOL. The capsule along the border of the optics might be a weak point against ocular massage.

The ophthalmic viscosurgical device (OVD) is an essential part of modern phacoemulsification surgery. Many times, OVDs are blamed for intraocular pressure spikes, toxic anterior segment syndrome, and capsular bag distension syndrome. To avoid these complications, we developed a technique in which phacoemulsification can be done without using OVDs. The irrigating cannula, on a continuous irrigation mode, was introduced through a side port, and capsulorhexis and incision construction were performed under an irrigating balanced salt solution. No hydroprocedure was performed. Phacoemulsification was done by chopping technique. At the end of the procedure, the intraocular lens was implanted by wound assistance technique under a continuous irrigation mode.

PURPOSE: To investigate whether the safety of intracameral moxifloxacin (IC-Mox) was equivalent to subconjunctival antibiotics (SC-Abs) in pediatric lens surgery. SETTING: The Hospital for Sick Children, Toronto, Canada. DESIGN: Retrospective consecutive cohort study. METHODS: This equivalence study compared 95% CI in the difference between the preoperative and postoperative safety variables of best corrected visual acuity (BCVA), intraocular pressure (IOP), central corneal thickness (CCT), endothelial cell density (ECD), corneal edema, and anterior chamber (AC) inflammation in IC-Mox with SC-Abs. The zone of clinical equivalence for BCVA was set at ±0.2 logarithm of the minimum angle of resolution, IOP at ±3 mm Hg, CCT at ±30 µm, and ECD at ±400 cells/mm. RESULTS: The charts of 358 patients undergoing lens-related surgeries were reviewed. Of 317 eyes (215 patients) included, 170 eyes received IC-Mox and 147 eyes had SC-Abs. The mean age was 4.9 and 5.1 years with a mean follow-up of 19 and 34.4 months (P < .001) in IC-Mox and SC-Ab groups, respectively. The 95% CIs for the change from preoperative to postoperative safety parameters between IC-Mox and SC-Abs were all in the zones of clinical equivalence (BCVA, P = 0.75; highest IOP in the first 6 weeks postoperatively, P = 0.27; IOP at the last visit, P = 0.74; CCT, P = 0.89; and ECD, P = 0.76). During the first 6 weeks postoperatively, there was no difference in corneal edema (P = .69) and AC flare (P = .4) between IC-Mox and SC-Ab groups, whereas AC cellular activity was significantly higher in the SC-Ab group (P = .028). CONCLUSIONS: IC-Mox prophylaxis in pediatric patients showed equivalent postoperative safety outcomes when compared with SC-Abs. The use of IC-Mox (250 µg) for endophthalmitis prophylaxis appears to be safe in the pediatric population.

A 36-year-old highly myopic woman was referred for management of both cataract and glaucoma. Her ocular history included retinal detachment repair in each eye, 9 years earlier in the right eye and 7 years earlier in the left eye. Although the patient did not remember specific details of the retinal surgery, she recalled that she had a "gas bubble" postoperatively in the right eye, but not the left eye. She also had a very dense nuclear cataract in the right eye, but only mild nuclear sclerosis in the left eye.At presentation, the patient's corrected distance visual acuity (CDVA) was 20/125 in the right eye, with a large myopic shift (-18.25 + 2.00 × 175). Her CDVA in the left eye was 20/20 (-11.00 + 1.00 × 20). It is notable that she is contact lens-intolerant.Her angle was wide open in each eye, and each optic nerve had severe myopic saucerization and cupping. The axial length was 28.5 mm and 28.7 mm in the right eye and left eye, respectively.The intraocular pressure (IOP) at presentation was 18 mm Hg in the right eye and 20 mm Hg in the left eye; each eye was treated with a topical ß-blocker, α-2 agonist, and a prostaglandin. The highest IOP measurements before treatment were 27 mm Hg and 25 mm Hg in the right eye and left eye, respectively. The pachymetry was 545 µm in the right eye and 540 µm in the left eye.Her visual fields and nerve fiber layers on optical coherence tomography (OCT) are shown in and , respectively.(Figure is included in full-text article.)(Figure is included in full-text article.)Cataract surgery was scheduled along with a coincident glaucoma procedure. It is noteworthy that intraoperatively, the right capsular bag was very loose. Indeed, the capsular bag could not be penetrated with the cystotome, which only dimpled the capsule severely but would not penetrate it. Accordingly, a super-sharp, #15 blade was used to pierce the capsule and initiate the capsulotomy.Whereas the zonule was obviously loose, the remainder of the procedure was completed without incident and the intraocular lens (IOL) placed in the capsular bag with perfect centration. It was unclear whether the loose zonule was a consequence of the patient's vitreoretinal surgery or whether there was a systemic cause for her zonulopathy. Although it was not suspected before the surgery, in retrospect, this patient had the classic body habitus of Marfan syndrome. Moreover, subsequent surgery in the fellow left eye found the zonule to be quite loose, but not as severe as in the right eye.How would you manage this patient's glaucoma? Given the finding of very loose zonular fibers, would you initiate a workup for Marfan syndrome? Certain microinvasive glaucoma surgery (MIGS) procedures are labeled for mild-to-moderate glaucoma. How strictly do you adhere to such labeling? Do you ever use a MIGS device in severe glaucoma?

PURPOSE: To present pilot results of the project in which the primary goal is to optimize way how to increase the quality of life of patients with the stable maculopathy by implanting intraocular Scharioth macular lens (SML) and modulating visual plasticity by a transcranial electrical stimulation (tES) together with a visual rehabilitation. MATERIALS AND METHODS: The study will include 20 patients with stable maculopathy (mainly age-related macular degeneration - AMD) who underwent cataract surgery in past and are eligible for SML implantation. The duration of the project is 3 years. During the first year of the project 17 patients were screened, SML implantation was recommended to 4 of them. They met the indication criteria of SML implantation and SML was implanted into the better seeing eye. The third postoperative day, the tES sessions started and were applied 20 times in the first month after SML implantation. The stimulation was delivered in double blind design (a stimulated and a shame group). Visual exercises and rehabilitation took place during the tES. The patients were examined ophthalmologically and also using electrophysiological methods. RESULTS: Before the implantation, the best corrected distance visual acuity was 0.23. At near it was Jaeger number 15 uncorrected, with +3.0 sphere dioptres J.No.10.5 and with +6.0 sph dpt J.No. 4.5. After the surgery and visual rehabilitation BCVA was 0.13 after 3 weeks, 0.2 after 2 months and 0.14 after 6 months. At near it was uncorrected J.No.7.5 after 3 weeks, J.No.7 after 2 months and J.No.5 after 6 months. CONCLUSION: According to a few participants, the impact of SML implantation together with intensive visual rehabilitation on vision at near and on satisfaction of patients with AMD could not be significantly established. Nevertherless, these patients are limited in their daily activities and SML is one of the solutions for them. The project is ongoing and blinded still, there is also a need of more participants to assess the effect of tES on vision, the results will be presented. We have proven the safety of methods used in the project.

PURPOSE: To determine the distribution and quantity of ophthalmic viscosurgical device (OVD) retained in the lens capsular bag after irrigation/aspiration (I/A) in experimental cataract surgery. SETTING: Department of Ophthalmology, Kashiwa Hospital, Jikei University School of Medicine, Japan. DESIGN: Experimental study. METHODS: Fifteen freshly enucleated porcine eyes were used. Sodium hyaluronate 1.0% (Healon) was mixed with a fixed concentration of silica nanoparticles encapsulating fluorescein isothiocyanate (labeled OVD), and it was injected separately into the capsular bag and injector cartridge for intraocular lens (IOL) insertion. After a 3-piece IOL (YA-60BBR) or a 1-piece IOL (iSert 255) was implanted within the capsular bag, OVD was removed by thorough I/A. Eyes that were injected with the labeled OVD into the capsular bag without IOL insertion were used as controls. The distribution of residual OVD in the capsular bag was observed under ultraviolet irradiation using Miyake-Apple view. Then, the excised capsular bag was dissolved in hydrogen fluoride, and silica concentration was measured quantitatively by elemental analysis. RESULTS: The quantity of residual OVD in the capsular bag was 243.1 µg ± 1.3 (SD) in the 3-piece IOL-implanted group, 383.8 ± 11.1 µg in the 1-piece IOL-implanted group, and 99.0 ± 1.3 µg in the control group. In the 1-piece IOL-implanted eyes, OVD in the form of clumps tended to remain near the center of the optic on the posterior side, and the quantity of residual OVD was significantly greater than in 3-piece IOL-implanted eyes (P < .05). CONCLUSION: The quantity of residual OVD after I/A could be determined indirectly using labeled OVD, and the quantity was significantly greater in 1-piece IOL-implanted eyes than in 3-piece IOL-implanted eyes.

PURPOSE: To analyze the posterior capsule rupture (PCR) rates among staff and trainee cataract surgeons, and the postoperative endophthalmitis (POE) rates in uncomplicated and complicated eyes both with and without intracameral moxifloxacin prophylaxis (ICMP). SETTING: Ten regional Aravind Eye Hospitals in India. DESIGN: Retrospective multicenter clinical registry within a single hospital network. METHODS: POE rates with and without ICMP were statistically compared for all eyes and separately for trainees versus staff, for phacoemulsification versus manual small-incision cataract surgery (M-SICS), and for a subgroup of eyes complicated by PCR or requiring secondary surgery. RESULTS: All cataract surgeries (2 062 643) performed during the 8-year period from 2011 to 2018 at the 10 regional Aravind Eye hospitals were included in the analysis. With ICMP, the overall POE rate declined from 692 (0.07%) of 993 009 eyes to 185 (0.02%) of 1 069 634 eyes (P < .001). This was independently significant for phacoemulsification and for M-SICS (P < .001). The overall PCR rate was 28 352 (1.37%) of 2 062 643 eyes, and it was statistically higher for trainees irrespective of surgical method (P < .001). Both staff and trainee surgeons had higher PCR rates with phacoemulsification than with M-SICS (P < .001). Absent ICMP, PCR increased the overall POE rate by more than 7-fold to 63 (0.43%) of 14 505 eyes. ICMP reduced the POE rate after PCR to 25 (0.18%) of 13 847 eyes (P = .002). This ICMP benefit was separately significant for both M-SICS (0.54% vs 0.26%, P = .01) and phacoemulsification (0.29% vs 0.06%, P = .005). The POE rate was especially high after secondary IOL implantation (0.90% without ICMP vs 0.34% with ICMP; P = .10). CONCLUSIONS: ICMP reduced the POE rate overall, with phacoemulsification, with M-SICS, and in eyes with PCR.

PURPOSE: To compare the rate of endophthalmitis of intracameral versus topical antibiotic prophylaxis for patients undergoing phacoemulsification at a single-centered, multispecialty ophthalmological institute. METHODS: A retrospective analysis of the rate of endophthalmitis by coding search within 90 days of cataract surgery in periods before (May 15, 2012-May 15, 2014) and after (April 30, 2015-April 30, 2017) intracameral antibiotics became the institution's preferred practice pattern for phacoemulsification. Clinical data were collected for each endophthalmitis case, including timing of onset, presenting symptoms and signs, culture results, treatment performed, and visual acuity outcome. RESULTS: The rate of postphacoemulsification endophthalmitis decreased from 0.18% (29 eyes among 16,201 cataract surgeries) to 0.07% (11 eyes among 16,325 surgeries) when the preferred method was changed from topical to intracameral antibiotics (P=0.004) with an odds ratio of 0.32. Endophthalmitis cases in the 2 groups had comparable visual acuity at initial presentation and at 3 months (P=0.86). The most commonly isolated organism in culture-proven cases of endophthalmitis in both groups was coagulase-negative staphylococcus. The rate of gram-positive endophthalmitis decreased from 0.08% to 0.02% with an odds ratio of 0.23 (P=0.012) while the rate of gram-negative cases remained similar. CONCLUSIONS: The use of intracameral antibiotics during cataract surgery was associated with a statistically significant reduction of postoperative endophthalmitis.

ABSTRACT We here in report the case of a patient subjected to cataract surgery through phacoemulsification under local anesthetic block, without intra-operative complications. The patient presented important visual impairment in the first post-operative day. Fundoscopy showed pallor resembling cherry-red spots at the macula. Fluorescein angiography did not depict signs of vascular occlusion and the spectral-domain optical coherence tomography showed increased reflectivity in the inner layers of the retina, thus suggesting local thickening and edema. The current case led to the diagnostic hypothesis of transient retinal arterial occlusion.
RESUMO Relatamos um caso de um paciente submetido a facectomia por facoemulsificação sob bloqueio anestésico peribulbar, sem intercorrências per-operatória, que apresentou no primeiro dia de pós-operatório baixa visual significativa. À fundoscopia observou-se palidez em aspecto de mácula em cereja. A angiofluoresceinografia não demonstrou sinais de oclusão vascular e a tomografia de coerência óptica mostrou aumento da refletividade das camadas internas da retina, sugerindo espessamento e edema local. No caso descrito foi aventada hipótese diagnóstica de oclusão arterial retiniana transitória.

A 32-year-old man presented with bilateral diminution of vision for 10 years. Visual acuity was light perception in both eyes with inaccurate projection in the oculus dextrus(OD) and accurate projection in the in oculus sinister (OS). Intraocular pressure was 6 and 12 mm Hg in the OD and OS, respectively. Slit-lamp examination revealed the presence of leucomatous corneal opacification with microcornea in oculus uterque (OU). Both eyes had a dislocated nucleus in the vitreous cavity on ultrasound B-scan with advanced cupping in the right eye. Ultrasound biomicroscopy revealed ciliary body atrophy in the OD and preserved ciliary processes (two quadrants) in the OS. In view of a partially preserved ciliary body function and a potential for gaining useful vision, we planned surgical intervention in the left eye. Deep anterior lamellar keratoplasty with pars planavitrectomy (PPV) and phacofragmentation of the nucleus was done. Donor lamellar graft was sutured after completion of PPV and nucleus fragmentation. The patient regained useful ambulatory vision postoperatively with clear corneal graft.

PURPOSE: To define factors affecting cataract surgery operating time for operating room planning, optimizing throughput, enhancing patient experiences, minimizing costs, and allocating training time. SETTING: Epsom and St. Helier University National Health Service Trust, London, United Kingdom. DESIGN: Retrospective case series. METHODS: All patients who had primary manual phacoemulsification cataract surgery from January 1, 2012, to December 30, 2016, were included. Combined anterior and posterior segment procedures and surgeons with fewer than 50 cases were excluded. Anonymized data collected were demographics, anesthesia, operating time, surgeon grade, case complexity, pupil size, pupil expander or capsular tension ring (CTR) use, intraocular lens type, posterior capsule or zonular fiber rupture or dialysis, vitreous loss, and automated anterior vitrectomy. RESULTS: From 11 067 cases, 9552 (86.3%) had a recorded operating time. The mean ± SD operating times in minutes were as follows: consultants 19 ± 10, junior 30 ± 11, intermediate 27 ± 12, senior trainees 24 ± 10, and fellows 31 ± 11. Operating time was significantly shorter for topical than for sub-Tenon or general anesthesia, especially among trainees. Consultant operating time remained unchanged with increasing case complexity, except for high-complexity cases. Small pupils, pupil expander or CTR use, posterior capsule or zonular fiber rupture or dialysis with or without vitreous loss (mean 45 ± 23) were associated with increased operating times. Iris hooks were associated with greater increases in operating time than Malyugin rings (16 minutes versus 6 minutes; P < .001). There was a modest 3-minute decrease in operating time among consultants over 5 years. CONCLUSION: Cataract surgery operating time was significantly influenced by anesthesia type, surgeon grade, high case complexity, pupil size, pupil expander use/type, CTR use, and intraoperative complications.

PURPOSE: To compare the effectiveness of intravitreal injection of triamcinolone acetonide-moxifloxacin (Tri-Moxi) to a standard eyedrop regimen in controlling postoperative inflammation, corneal edema, and the rate of high intraocular pressure (IOP) among cataract patients. SETTING: Loma Linda University Eye Institute, California, USA. DESIGN: Retrospective longitudinal comparative study. METHODS: The electronic medical records of patients who underwent cataract surgery using triamcinolone acetonide-moxifloxacin injection along with a postoperative nonsteroidal antiinflammatory drug drop were reviewed (Group 1). Group 1 was compared with patients who received a standard eyedrop (Group 2) in terms of intraocular inflammation and corneal edema severity, and the rate of high IOP, postoperatively. RESULTS: A total of 1195 consecutive eyes (Group 1 [681 eyes], Group 2 [514 eyes]) of 919 patients were included in the study. The anterior chamber cell reaction severity decreased by 34.0% and 35.7% at 1 week and 1 month, respectively, after surgery following triamcinolone acetonide-moxifloxacin injection compared with standard eyedrop therapy (P = .001 and P = .02, respectively). Group 1 was associated with increased severity of corneal edema (odds ratio, 1.48; P = .001) on postoperative day 1, with no statistically significant difference at 1 week and 1 month postoperatively (P = .25 and P = .48, respectively). There was no statistically significant difference in the rate of high IOP between the two groups at different timepoints postoperatively. CONCLUSIONS: Triamcinolone acetonide-moxifloxacin injection is an effective method to control intraocular inflammation after cataract surgery. It is a promising substitute for standard eyedrop therapy, especially for patients who have poor compliance with eyedrop usage.
