Ab interno implantation of glaucoma drainage devices tubes in the posterior chamber.

BACKGROUND: Glaucoma drainage device (GDD) implantation in the anterior chamber are associated with corneal complications. We describe a novel technique to implant GDD tubes in the posterior chamber of pseudophakic eyes. METHODS: Ten patients with glaucoma who required GDD tube implantation were included. RESULTS: The new technique begins with the passage of one of two straight needles existing at each end of a 10-0 Polypropylene suture through the GDD tube. A 23-gauge needle then is inserted at an angle 180° away and passed from the anterior to the posterior chamber and finally through the sclera. The two suture straight needles from the 10-0 Polypropylene suture are positioned in the lumen of the 23-gauge needle. The 23-gauge needle is then extracted from the eye by passing the 2 needles through the lumen. The suture remains inside the posterior chamber, and the tube is inserted into the posterior chamber by pulling on the suture from the other side. No intra-operative complications were found such as bleeding, vitreous tube placement, bent tubes, etc. CONCLUSIONS: This surgical procedure to implant a tube into the posterior chamber of the pseudophakic eyes is uncomplicated and facilitates the insertion of the flexible tube into the posterior chamber. This eliminates the tendency of the tube to enter the vitreous as the tube is always placed in the posterior chamber away from the cornea.

Localized calcification of hydrophilic acrylic intraocular lenses after posterior segment procedures.

PURPOSE: To describe the clinical and laboratory findings in a series of cases of hydrophilic acrylic intraocular lens (IOL) opacification after posterior segment procedures. SETTING: John A. Moran Eye Center, University of Utah, Salt Lake City, USA. DESIGN: Experimental study. METHODS: Thirty hydrophilic acrylic IOLs were explanted after various posterior segment procedures (pars plana vitrectomy, intravitreal anti-vascular endothelial growth factor injections) because of localized central anterior surface and subsurface optic opacification associated with decreased visual function. Once received by the laboratory in the dry state or in fixative by the explanting surgeons, microscopic, histochemical (alizarin red), and surface analysis (scanning electron microscopy [SEM], energy-dispersive X-ray spectroscopy [EDS]) evaluations were performed on the IOLs. The surgeons were sent a questionnaire to obtain information pertinent to each case. RESULTS: Of the 30 explanted IOLs, 9 hydrophilic acrylic designs from 7 different manufacturers were identified. Gross microscopy and light microscopy showed granular deposits in a dense round pattern of distribution within the margins of the capsulorhexis or pupil on the anterior surface/subsurface of the IOLs. The granules stained positive for calcium with alizarin red. On SEM coupled with EDS, the granular deposits were found to comprise calcium and phosphate. CONCLUSIONS: A localized pattern of anterior surface/subsurface calcification was seen on hydrophilic acrylic IOLs from various manufacturers. The calcification resembled the pattern seen on calcified IOLs after anterior segment procedures using intracameral injections of air or gas. This calcification of hydrophilic acrylic IOLs is likely the result of blood-aqueous barrier breakdown from repeated intraocular procedures.

Clinical outcome of a nonvalved Aurolab aqueous drainage implant in posterior segment versus anterior chamber.

Purpose: To evaluate the outcome of a nonvalved Aurolab aqueous drainage implant (AADI) in the management of refractory glaucoma. Methods: Retrospective case series of patients with refractory glaucoma underwent AADI implantation in posterior segment (PS group) or anterior chamber (AC group) with minimum follow-up of 1 year. Primary outcome criterion was success, defined as intraocular pressure (IOP) <18 or >6 mm Hg or IOP reduced to <20% from baseline, for two consecutive visits after 3 months. Failure was defined as inability to meet IOP criteria, any additional glaucoma surgery, loss of light perception, and implant explantation. Secondary outcome criteria compared groups based on mean IOP, mean glaucoma medication use, best-corrected visual acuity, and complications at each postoperative visit. Results: In the AC and PS group of 64 patients, 32 tubes each were placed. Preoperative mean IOP was 37.41 ± 8.6 and 43.38 ± 10.3 mm Hg in AC and PS, respectively. Postoperatively IOP reduced to 14.22 ± 4.9 and 15.21 ± 8.1 mm Hg in AC and PS groups, respectively (P < 0.001). Preoperative mean antiglaucoma medication changed from 2.56 ± 0.9 and 3.44 ± 0.5 to 1.03 ± 0.9 and 1.67 ± 0.5 in AC and PS, respectively, postoperatively (P < 0.001). No significant change in VA was noted in either group. At 12 months, success rate was 84% in AC group and 72% in PS group, with PS group having 2.63 times higher hazard (risk) of failure than AC group. Conclusion: AADI implantation in PS or AC is a safe and effective method for IOP control in refractory glaucoma with its low cost being of significance in developing countries.

Comparative analysis of clinical outcomes between two types of posterior chamber phakic intraocular lenses for correction of myopia and myopic astigmatism.

Purpose: To compare clinical outcomes following implantation of two types of posterior chamber phakic intraocular lenses: Visian™ Implantable Collamer Lens with Centraflow (ICL, V4C Staar Surgical, Nidau, Switzerland) and Implantable Phakic Contact Lens (IPCL, V1, Caregroup Sight Solution, India) for the correction of myopia and myopic astigmatism. Methods: This retrospective case series included eyes which underwent phakic intraocular lens implantation with a minimum follow-up period of 1 year. Visual outcomes including safety, efficacy, refractive predictability, and stability were compared at 1 week and at 1, 6, and 12 months' postoperative visit. Complications and adverse events were analyzed. Results: The study included 119 and 203 eyes in the IPCL and ICL groups, respectively. At 1-year postoperative visit, median corrected distance visual acuity was 0.10 (interquartile range [IQR] 0,0.10) and 0 (IQR 0,0) in the IPCL and ICL cohorts, respectively (P = 0.066). An uncorrected visual acuity of 20/32 or better was achieved in 86.5% and 88.67% of the eyes, respectively (P = 0.574). Ninety and 94% of the eyes achieved a postoperative manifest spherical equivalent within ± 0.5D (P = 0.169, χ2 test). Three eyes (2.52%) in the IPCL group versus one eye (0.49%) in the ICL group developed visually significant cataract requiring surgical intervention (P = 0.113). No vision-threatening complications were noted in either cohort. The mean follow-up period was 94.69 ± 32.45 and 102.67 ± 61.82 weeks, respectively. Conclusion: Both groups demonstrated similar efficacy and safety profile. The IPCL is an effective and economically viable option for the correction of myopia.

23-gauge transconjunctival vitrectomy for posterior segment intraocular foreign bodies.

BACKGROUND: This study is a report of the outcomes of 23-gauge (G) transconjunctival vitrectomy (TV) performed to treat a posterior segment intraocular foreign body (IOFB). METHODS: The data of 14 eyes of 14 patients who underwent 23-G TV for the removal of a posterior segment IOFB were reviewed in this study. Surgery was initiated with a 23-G system in each case and the posterior segment IOFB was removed through the enlarged sclerotomy site. All of the patients were male. The mean age of the patients was 36.6+-11.0 years. RESULTS: The foreign body (FB) was located in the vitreous in 11 eyes and in the retina in 3 eyes. Before the 23-G TV, complicated cataract was detected in 6 eyes, vitreous hemorrhage was detected in 5 eyes, and retinal detachment was detected in 1 eye. The size of the FB ranged from 3 mm to 7 mm; 12 of the FBs were metallic and 2 were glass. Silicone oil was used as a tamponade agent in 5 eyes and gas tamponade (C3F8) was used in 4 eyes. The mean follow-up time was 8.15+-2.9 months. At the last examination, of the 14 eyes included in the study, the visual acuity (VA) was 0.1 or better in 10 eyes and less than 0.1 in 4 eyes because 2 eyes had peri-macular scar, 1 eye had massive sub-epiretinal membrane and 1 eye had retinal re-detachment. CONCLUSION: 23-G TV is seen as an effective and minimally invasive technique to remove posterior segment IOFBs.

Posterior Chamber Phakic Intraocular Lens Implantation for the Correction of Myopia and Myopic Astigmatism: A Retrospective 10-Year Follow-up Study.

PURPOSE: To assess the 10-year clinical outcomes of implantable collamer lens (ICL) implantation for myopia and astigmatism. DESIGN: Retrospective observational case series. METHODS: This study included 114 eyes of 61 patients who underwent ICL implantation for correction of myopia and myopic astigmatism. We assessed the safety, efficacy, predictability, stability, and adverse events preoperatively, at 6 months (106 eyes) and 1 (94 eyes), 3 (58 eyes), 5 (65 eyes), 8 (89 eyes), and 10 (70 eyes) years postoperatively. Only the eyes with clinical data available at each follow-up time were analyzed. RESULTS: The mean logMAR uncorrected and corrected distance visual acuities were -0.01 ± 0.24 and -0.18 ± 0.07 at 10 years postsurgery. The mean indices for safety and efficacy were 0.88 ± 0.15 and 0.66 ± 0.26, respectively. At 10 years postsurgery, 71.4% and 87.1% of the eyes were within 0.5 and 1.0 diopters (D), respectively, of the attempted spherical equivalent correction. The mean intraocular pressure was 13.1 ± 2.4 mmHg preoperatively and 13.1 ± 2.9 mmHg at 10 years postoperatively. The mean endothelial cell loss was 5.3% at 10 years postsurgery. Twelve of 114 eyes (10.5%) developed anterior subcapsular cataract during 5-10 years' follow-up; among these, 4 eyes (3.5%) were symptomatic and ICL explantation and phacoemulsification surgery were performed. No vision-threatening complications occurred during the observation period. CONCLUSION: ICL implantation offered good overall outcomes in all measures of safety, efficacy, predictability, and stability for the correction of myopia and myopic astigmatism throughout a long-term follow-up period of 10 years.

Calcification of hydrophilic acrylic intraocular lenses following secondary surgical procedures in the anterior and posterior segments.

AIMS: To report 15 cases of intraocular lens (IOL) calcification following intraocular surgery and to identify common risk factors. METHODS: A retrospective case review of patients with IOL calcification reported from the Royal Victorian Eye and Ear Hospital, Melbourne, Australia, and six surgeons in private practice in the Australian states of Victoria, New South Wales and Queensland. RESULTS: 15 cases of IOL calcification were identified. Eight cases were in hydrophilic acrylic IOLs and seven in hydrophilic acrylic IOLs with hydrophobic surface properties. Five cases occurred following intraocular injection of gas during endothelial keratoplasties. Two cases occurred following pars plana vitrectomy where gas was used. The remaining eight cases did not involve the injection of any intraocular gas; six cases were following trabeculectomy surgery, and two cases were after insertion of a 'piggyback' sulcus IOL. In each case, the calcification had a characteristic pattern, being centrally placed in the pupillary zone, mainly affecting the anterior lens surface. CONCLUSION: The aetiology of IOL calcification is not fully understood, although there are known risk factors such as using hydrophilic acrylic materials and the use of intraocular gas. Surgical consideration of a patient's ocular comorbidities before IOL implantation is an important tool to mitigate some of this risk.

Clinical characteristics and prognostic factors of posterior segment intraocular foreign body in a tertiary hospital.

BACKGROUND: To identify the clinical characteristics, prognostic factors and visual outcomes in posterior segment IOFBs patients managed by PPV in a tertiary hospital. METHODS: A retrospective chart review was performed for 56 patients, who had PPV for IOFBs removal between November 2013 and November 2015. The mechanisms of injury, the nature of the IOFBs, the BCVA before and after the surgery, the penetrating site and the complications of the surgery were all collected. Univariate analyses were conducted to evaluate the prognostic factors. RESULTS: The mean age of the patients was 36.4 years. The nature of IOFBs was mainly metal. Most injuries were commonly caused by hammering the metal. The mean preoperative VA was 2.30 logMAR, and mean final VA was 0.92 logMAR. From univariate analysis, good visual outcome was correlated with the good visual acuity before surgery and poor visual outcome was correlated with the macular break and multiple surgeries. CONCLUSIONS: In a tertiary hospital of eastern China, most cases of IOFBs were work-related. The prognosis of the patients was really well in the patients with good presenting visual acuity. Nevertheless the prognosis was not good for those patients who had macular injury or underwent several surgeries because of retinal detachment, epiretinal membrane or proliferative vitreous retinopathy. Good facilities for eye protection are urgently in demand for the workers indeed.

The outcomes of bimanual posterior segment intraocular foreign body removal with vitrectomy and description of two different handshake techniques: A single surgeon case series.

PURPOSE: To evaluate the outcomes of bimanual intraocular foreign body (IOFB) removal with vitrectomy and describe the techniques of "active aspiration to forceps" and "forceps to forceps handshake" for IOFB removal. METHODS: Retrospective, interventional, single surgeon case series. The patients who had an IOFB and underwent vitrectomy with bimanual IOFB removal techniques and had a minimum follow-up period of 12 months were included. The main outcome measure was the functional and anatomical results of the bimanual surgical techniques. RESULTS: Twenty eyes were included. The mean follow-up time after surgery was 16.5±3.6 months (range 12-24 months). The baseline best corrected visual acuity (BCVA) was light perception in 8 eyes (40%), hand motions in one eye (5%), and≥1.0LogMAR in 11 eyes (55%). BCVA improved in 14 eyes (70%); was stable in 3 eyes (15%), and decreased in 3 eyes (15%). CONCLUSIONS: Both bimanual handshake techniques were safe and effective methods in the surgical treatment of IOFBs<5mm in size. The "active aspiration to forceps handshake" technique might be a gentle technique for the removal of IOFBs that are located on the surface of or trapped within the retina.

Combined Keratoplasty, Pars Plana Vitrectomy, and Flanged Intrascleral Intraocular Lens Fixation to Restore Vision in Complex Eyes With Coexisting Anterior and Posterior Segment Problems.

PURPOSE: To restore vision in complex eyes with coexisting anterior and posterior segment problems, combined corneal transplantation (penetrating keratoplasty [PK] or Descemet-stripping automated endothelial keratoplasty [DSAEK]), pars plana vitrectomy (PPV), and/or flanged intrascleral intraocular lens (IOL) fixation, designated vitreocorneal surgery are performed. In this study, we evaluated the usefulness of vitreocorneal surgery for eyes with complex comorbidities. METHODS: Thirteen consecutive eyes in 13 patients with coexisting corneal pathology (ie, corneal scarring, bullous keratoplasty, corneal laceration) and posterior segment pathology (ie, aphakia without capsular support, retinal detachment, intravitreal foreign body) underwent vitreocorneal surgery. Visual outcomes, intraoperative and postoperative complications, and additional surgery were retrospectively evaluated. RESULTS: Vitreocorneal surgery included PK + PPV + intrascleral IOL fixation (n = 5), PK + PPV (n = 3), PK + intrascleral IOL fixation (n = 1), DSAEK + intrascleral IOL fixation (n = 1), and DSAEK + PPV + intrascleral IOL fixation (n = 3). An intraoperative Eckardt temporary keratoprosthesis use enabled safe PPV. No vitreoretinal/IOL complications occurred. One eye required repeat DSAEK to repair endothelial graft detachment and inversion. In 3 eyes, secondary glaucoma was subsequently treated by glaucoma drainage device implantation through the pars plana. Mean best spectacle-corrected visual acuity (logMAR) improved from 1.8 ± 0.9 preoperatively to 1.1 ± 0.6 at 11.2 ± 14.6 months postoperatively (P = 0.002). Postoperative refraction was -0.68 ± 2.56 D (spherical equivalent). CONCLUSIONS: PK or DSAEK with PPV and/or flanged intrascleral IOL fixation is useful for complex eyes with coexisting anterior and posterior segment problems.

Prognostic value of ocular trauma score for open globe injuries associated with metallic intraocular foreign bodies.

BACKGROUND: The prognostic value of the ocular trauma score (OTS) in patients who underwent 23-gauge pars plana vitrectomy (23-G PPV) for surgical removal of posterior segment metallic intaocular foreign bodies (IOFB) was evaluated. METHODS: Patients who underwent 23-G PPV for surgical removal of retained metallic IOFBs were retrospectively analyzed. OTS score for each patient was calculated and raw scores were converted to their corresponding OTS categories. The final VAs in study patients were compared with their respective OTS categories. RESULTS: Twenty-five eyes from 25 patients were examined. Twenty-four (96%) of the patients were male, and the mean age was 34 ± 12 years. The time from injury to 23-G PPV was 9 ± 4 days. Fourteen (56%) patients had zone 1 trauma, eight (32%) patients had zone 2 trauma, and three (12%) patients had zone 3 trauma. Postoperative visual acuity was ≥ 20/200 in 14 (56%) of the patients and ≥ 20/40 in seven (28%) eyes. At the final visit, anatomical success was achieved in 86% of patients with retinal detachment at presentation. No statistically significant differences were found between our final VAs and OTS scores. CONCLUSION: OTS, which provides prognostic information after general ocular trauma, may also provide valuable prognostic information for patients who undergo 23-G PPV for the surgical removal of metallic posterior segment IOFBs.

Changes in anterior chamber volume after implantation of posterior chamber phakic intraocular lens in high myopia.

BACKGROUND: The present study aimed to assess changes in, and the factors that influence, anterior chamber volume (ACV) after implantable contact lens (ICL) implantation in high myopia eyes using a Pentacam. METHODS: The study sampled 26 high myopia patients (45 eyes) who were treated with ICL implantation. These patients were followed for an average of 4.28 months postoperatively. ACV was measured with a Pentacam preoperatively and at 3 months postoperatively. The data were analyzed by paired samples Wilcoxon signed-rank test. Generalized estimating equation (GEE) model adjusting within-patient intereye correlations in addition to Pearson's and Spearman's correlation tests were performed to determine associations. RESULTS: The mean ACV was 198.33 ± 33.08 mm3 before surgery and 118.65 ± 17.70 mm3 after surgery. A significant decrease of 79.68 mm3 (40.18%) (Z = 5.841, P <  0.001) was detected. Positive correlations were found between ACV changes and ICL central vault (r = 0.528, P <  0.001) and preoperative anterior chamber depth (ACD) (r = 0.665, P <  0.001). There were positive correlations between postoperative ACV and postoperative anterior chamber angle (ACA) at 3:00 o'clock (r = 0.448, P = 0.002) and at 9:00 o'clock (r = 0.405, P = 0.006). GEE regression model showed that postoperative ACV significantly positively correlated with preoperative ACV (P = 0.002), ACD (P = 0.002) and horizontal ACA (P = 0.005) and negatively correlated with ICL central vault (P <  0.001). CONCLUSION: Complementary to vault and ACD, ACV is a sensitive parameter with certain value of preoperative assessment and postoperative monitoring in ICL implantation.

Refractive outcomes and optical quality after implantation of posterior chamber phakic implantable collamer lens with a central hole (ICL V4c).

BACKGROUND: To investigate refractive outcomes and optical quality after implantation of posterior chamber phakic implantable collamer lens with a central hole (ICL V4c) to correct high myopia. METHODS: Sixty seven eyes of 38 patients who underwent ICL V4c implantation were enrolled. The mean preoperative spherical equivalent (SE) was - 12.44 ± 3.15 D (range: - 6.63 to - 20.50 D). The refractive outcomes and optical quality of the eyes at postoperative 1 and 3 months were evaluated and compared. RESULTS: At 3 months postoperatively, the mean safety and efficacy indexes were 1.33 ± 0.22 and 1.14 ± 0.23, respectively. The mean SE was - 0.32 ± 0.52 D; no patient lost 1 or more lines of corrected distance visual acuity (CDVA), 13% remained unchanged, 45% gained 1 line and 42% gained 2 or more lines. The mean modulation transfer function cutoff frequency (MTFcutoff), Strehl in two dimensions ratio, and objective scatter index (OSI) were 38.20 ± 9.96 cycles per degree, 0.21 ± 0.06, and 1.00 ± 0.73, respectively. No significant difference was found in any of the above parameters (P > 0.05) between 1 and 3 months. The postoperative intraocular pressure (IOP) did not change when compared with preoperative values (P > 0.05). CONCLUSIONS: ICL V4c implantation is a safe, effective, and stable solution for high myopia. Patients will acquire high and stable postoperative optical quality. ICL V4c implantation has little influence on IOP.

SILICONE MICROTUBE-ASSISTED SCLERAL FIXATION OF A POSTERIOR CHAMBER INTRAOCULAR LENS.

PURPOSE: To report a novel technique for intrascleral fixation of a posterior chamber intraocular lens using a silicone microtube to manipulate the haptics into position. METHODS: Intrascleral fixation was performed in six eyes and the results evaluated in this retrospective case series. A silicone microtube with a 0.2-mm external diameter was passed from a sclerocorneal incision through the chamber and a sclerotomy made using a 30-gauge needle. The tips of the intraocular lens haptics were connected to the silicone microtube outside the eye. After the intraocular lens was injected into the posterior chamber, the haptics were drawn through the scleral incision through their attachment to the silicone microtube. RESULTS: The mean postoperative corrected visual acuity was 0.62 logarithm of the minimum angle of resolution (20/43) with a mean refraction error of -0.06 ± 0.4 diopter, which did not differ significantly (P = 0.53) from the expected value. The postoperative complications included transient ocular hypotension, vitreous hemorrhage, and choroidal detachment. CONCLUSION: Our technique using a silicone microtube reduces the number of intraocular procedures compared with previous methods using forceps or needles for moving the intraocular lens haptics from the posterior chamber to the outside through sclerotomies.

QUIET PLEASE! Effect of distraction on simulated posterior segment surgical performance.

PURPOSE: To determine the effect of distraction on posterior segment surgical performance using a virtual reality simulator in expert and novice ophthalmic surgeons. METHODS: Twenty subjects were given 6 min to read an unpublished research paper and then were randomized into two groups. Group 1 subjects were allowed 3 min to complete a standardized vitreoretinal simulated task undistracted. Group 2 subjects were asked six questions on the research paper whilst completing the same task. Each subject then performed the alternate scenario. Finally, all participants were asked six questions on the research paper whilst not operating. RESULTS: There was no evidence of a difference in the odometer values (p = 0.127), cognitive task score (p = 0.390) or overall surgical task scores (p = 0.113) between the two groups. The time taken by the distracted group was significantly greater (95% CI -26.03 to -1.67, t-test p = 0.028). CONCLUSION: Distraction significantly increases the time taken to perform a simulated vitreoretinal surgical task for all grades of surgeon. More studies are required to understand the impact on different types of distraction on surgical performance.

Posterior chamber phakic intraocular lens implantation: comparative, multicentre study in 351 eyes with low-to-moderate or high myopia.

AIM: To compare the clinical outcomes of posterior chamber phakic intraocular lens implantation with a central hole (Hole Implantable Collamer Lens (ICL), STAAR Surgical) for low-to-moderate myopia and for high myopia. METHODS: This multicentre retrospective case series comprised 351 eyes of 351 consecutive patients undergoing ICL implantation. Eyes were divided into groups based on preoperative degree of myopia: group 1; 57 eyes, manifest spherical equivalent less than -6 dioptres (D), and group 2; 294 eyes, -6 D or more. Safety, efficacy, predictability, stability and adverse events were compared preoperatively; and at 1 day, 1 week and 1, 3, 6 and 12 months postoperatively, RESULTS: Uncorrected and corrected visual acuities were -0.17±0.14 and -0.21±0.10 logMAR in group 1, and -0.16±0.09 and -0.21±0.08 logMAR in group 2, 1 year postoperatively. In groups 1 and 2, 98% and 99% of eyes were within 1.0 D of the targeted correction. Manifest refraction changes of -0.12±0.34 D (group 1) and -0.18±0.43 D (group 2) occurred from 1 day to 1 year. ICL exchanges were necessary in two eyes (0.7%) in group 2. No vision-threatening complications occurred at any time. CONCLUSIONS: The ICL performed well for the correction of both low-to-moderate myopia and high myopia throughout the 1-year observation period. The clinical outcomes of ICL implantation for low-to-moderate myopia are essentially equivalent to those for high myopia.

Surgical Management and Outcome of Open Globe Injuries with Posterior Segment Complications: A 10-Year Review.

PURPOSE: To describe the characteristics, management, and outcomes of open globe injured (OGI) eyes that underwent pars plana vitrectomy (PPV) for posterior segment complications. METHODS: Retrospective chart review of cases that underwent PPV for posterior segment complications associated with OGI between 2003-2012 at University Hospital, Newark, NJ. RESULTS: 120 eyes were identified and classified as follows: "early retinal detachment (RD)" (within 30 days of OGI), 64 (53%) eyes; "delayed RD" (≥30 days after OGI), 30 (25%) eyes; and "no RD," 26 (22%) eyes. Injuries included penetrating (39 (33%) eyes), rupture (60 (50%) eyes), and penetrating wounds with retained intraocular foreign body (21 (17%) eyes). Injuries in Zones I, II, and III were seen in 40 (35%) eyes), 38 (34%) eyes, and 35 (31%) eyes, respectively, with statistically different ocular trauma scores (p<0.01) associated with each zone of injury. Mean presenting and final logMAR VA were 2.20± 0.63 and 1.87 ±0.60, respectively (p<0.01), with a mean follow-up of 3.2 years. Final overall anatomic success after surgeries was 98% for early RD and 95% for delayed RD. CONCLUSION: Despite a high anatomic success rate, the overall functional success rate for eyes with posterior segment trauma that undergo PPV is poor and comparable to other studies.

Sutureless glueless intrascleral fixation of posterior chamber intraocular lens: Boon for aphakic.

PURPOSE: To report results of intrascleral fixation of 3-piece IOL without the help of suture and glue. METHODS: Study included intrascleral fixation of haptic in 50 eyes by T-fixation technique. Preoperative and postoperative visual acuity, slit lamp and fundus examination, applanation tonometry, keratometry, biometry, optical coherence tomography, Scheimpflug imaging were done for extensive evaluation. Qualitative and quantitative data were summarized in the form of proportion and mean and standard deviation, respectively. The significance of difference was measured by Chi-square test or unpaired t-test or ANOVA whichever is appropriate. P < 0.05 was considered as statistically significant. RESULTS: There was one case in which haptic broke during handshake maneuver and another IOL was required. Postoperative complications included corneal edema (4%), increased intraocular pressure (6%), cystoid macular edema (2%), decentration (4%), and dislocation (2%), which were all managed to the level of good visual recovery. There was no significant change in corneal astigmatism. There was significant change found in best-corrected visual acuity and uncorrected visual acuity after surgery. CONCLUSION: This modified technique seems to be a good alternative in IOL implantation in eyes with deficient capsules in view of the decrease in the learning time and surgical time and risk for complications.
