Objective: To evaluate mean decrease in Corneal Endothelial cell Density (CED) after phacoemulsification in patients with different Anterior Chamber Depths (ACDs) and Axial Lengths (ALs). Methods: This prospective stratified controlled study was conducted at PNS Shifa Hospital, Karachi. One hundred eyes of 90 patients, scheduled to undergo phacoemulsification surgery, were included. AL and ACD of each patient were calculated preoperatively using IOL Master. Cataracts were classified according toLens Opacities Classification System III (LOCS III) giving nuclear opalescence (NO) grades on slit lamp examination and only patients with grades NO2 and NO3 were included.Eyes were divided into two groups according to ACD and AL: Group-I: ACD 2.0mm – 3 mm and AL 22mm – 23.5mm; Group-II: ACD 3.1 mm -4.0 mm and AL 23.6mm – 25mm. CED measurements were done preoperatively and 2 month postoperatively using specular microscopy. The difference in CED change (Endothelial Cell Loss) between the two groups after surgery was analyzed using SPSS, v 22; IBM Corporation, Armonk, NY. Results: Differences in gender, laterality, age and preoperative CED between two groups were not significant. Difference in postoperative CED was also not significant, however difference in mean change and mean frequency change in CED between two groups was found to be statistically significant. Conclusion: ACD and AL affect the CED during phacoemulsification and Intraocular Lens(IOL) implantation and can be considered as risk factors of peroperative endothelial cell loss.

Purpose: To assess the association between anterior chamber depth and endothelial cell loss after phacoemulsication Material and Methods: Ninety patients were recruited for this comparative type of observational study who were further divided into 3 groups according to anterior chamber depth (ACD). All patients underwent phacoemulsication procedure and intraocular implantation. Postoperatively endothelial cell loss (ECL) was calculated by measuring percentage decrease in endothelial cell density of central cornea and regression coefcient between ACD and ECLwas assessed in each group. Results: Endothelial cell loss was signicantly higher in shallow anterior chambers to other groups and the association between ACD and ECLwas signicant only in shallow anterior chamber depth group. Conclusion: Eyes with shallow anterior chamber depth are at higher risk for endothelial cell damage and shows an association between ACD and ECLwhen compared to deep anterior chamber depth.

Purpose: To investigate the ocular biometric changes after uneventful Ahmed glaucoma valve implantation. Methods: Patients with refractory glaucoma who were candidate for Ahmed valve surgery were prospectively included in this study. Patients with a history of any kinds of corneal surgery were excluded. Refractive status, intraocular pressure, axial length, anterior chamber parameters including anterior and posterior mean keratometry, central corneal thicknesses, and anterior chamber depth, anterior chamber volume, and anterior chamber angle were evaluated at baseline and 1 and 3 months after surgery. Results: A total of 20 eyes from 20 patients were included. Mean intraocular pressure at baseline was 33.4 ± 12.3 mm Hg that significantly decreased to 14.6 ± 6.2 mm Hg at 1 month and 13.5 ± 4.3 mm Hg at 3 months after Ahmed glaucoma valve implantation ( p < 0.001). Mean number of medications was 3.6 ± 1.3 at baseline which significantly decreased to 1.0 ± 1.3 at 3 months after Ahmed glaucoma valve implantation ( p < 0.001). Axial length decreased significantly from 23.69 ± 1.95 to 23.47 ± 1.91 mm ( p < 0.001) at month 3. There were no significant changes in other parameters such as mean spherical equivalent, anterior chamber volume, anterior chamber angle, anterior chamber depth, and keratometry at the end of month 3 after surgery ( p > 0.05 in all). Conclusion: Ahmed glaucoma valve implantation had a significant effect on axial length at 3 months after surgery but its effect on keratometry and other anterior chamber parameters was not significant.

Purpose: To report a case of fully dislocated XEN Gel Implant device into the anterior chamber, 18 months after its implantation and its impact on endothelial cell density. Result: A 75-year-old man with a history of multiple glaucoma surgeries during the last three years presented with an entirely dislocated XEN Gel implant into the anterior chamber. An endothelial cell density reduction was observed over 18 months. Thus, the implant was removed. In the short-term after surgery, the endothelial cell loss rate reduced. Conclusion: XEN Gel Implant can dislocate into the anterior chamber, increasing endothelial cell loss in an eye already underwent multiple surgical procedures with subsequent adverse events. Therefore, if the implant seems displaced, the endothelial cell density should be monitored, and the length of the free-tube segment within the anterior chamber should be measured, during the patient’s follow-up.

Purpose. To evaluate anterior segment’s structures by Pentacam in patients with tilted disc syndrome (TDS).Methods. Group 1 included forty-six eyes of forty-six patients who have the TDS. Group 2 including forty-six eyes of forty-six cases was the control group which was equal to the study group in age, gender, and refraction. A complete ophthalmic examination was performed in both groups. All cases were evaluated by Pentacam. The axial length (AL) of eyes was measured by ultrasound. Quantitative data obtained from these measurements were compared between two groups.Results. There was no statistically significant difference for age, gender, axial length, and spherical equivalent measurements between two groups (p=0.625,p=0.830,p=0.234, andp=0.850). There was a statistically significant difference for central corneal thickness (CCT), corneal volume (CV), anterior chamber angle (ACA), and pupil size measurements between two groups (p=0.001,p=0.0001,p=0.003, andp=0.001). Also, there was no statistically significant difference for anterior chamber depth (ACD), anterior chamber volume (ACV), and lens thickness (LT) measurements between two groups (p=0.130,p=0.910, andp=0.057).Conclusion. We determined that CCT was thinner, CV was less, and ACA was narrower in patients with TDS. There are some changes in the anterior segment of the eyes with tilted disc.
