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 compare femtosecond laser-assisted cataract surgery (FLACS) versus conventional phacoemulsification in shallow anterior chamber cataract patients with glaucoma or zonulysis. Methods. This was a single-center retrospective review of cataract surgeries in shallow anterior chamber and glaucoma patients between January 2016 and December 2018 in which a LenSx femtosecond laser was used. The outcome measures included pre- and postoperative uncorrected and corrected distance visual acuity (UDVA and CDVA), intraocular pressure (IOP), endothelial cell density (ECD), endothelial cell loss (ECL), and object scatter index (OSI). Results. One hundred and six eyes of 106 patients with a mean anterior chamber depth of 1.54 ± 0.51 mm were included in this study. Among them, 26 (23.2%) had zonulysis and 18 eyes had capsular tension ring implantation in general. The percentage of capsular tension ring implantation was statistically significantly lower in the FLACS group ( P  = 0.027). The UDVA, CDVA, ECD, and IOP were not statistically significant between the two groups at all time points. The postoperative ECL and OSI of the FLACS group was better than those of the conventional group ( P  < 0.01). Conclusions. FLACS can reduce ECL and improve visual quality compared to the conventional phacoemulsification in shallow anterior chamber patients. Also, it has the trend of reducing the use of capsular tension rings in subluxated cataracts. It is an ideal choice for patients with complicated cataract such as with shallow anterior chambers, glaucoma, and zonulysis.

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 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.

Insertion Techniques

Descemet’s stripping endothelial keratoplasty has emerged as the treatment of choice for primary and secondary endothelial failure. One of the most crucial portions of the procedure is introducing the donor lenticule into the anterior chamber. Numerous techniques and instruments have been developed in an attempt to simplify the incision and reduce endothelial cell loss.
