ABSTRACT: Purpose
To describe a novel technique of phacoemulsification in morgagnian cataract using capsular tension ring (CTR).Methods
This was a retrospective, non-comparative, clinical interventional study. Patients with hypermature morgagnian cataract who had undergone CTR-assisted phacoemulsification were included in the study. After capsulorhexis, CTR was inserted in a clockwise manner to stabilize the capsular bag in each case. Phacoemulsification was then performed using either horizontal chopping or vertical chopping. We have used the CTR in these cases without any obvious lens subluxation in order to perform safe emulsification of the nuclear pieces in the capsular bag. We have performed the procedure successfully in eleven eyes with hypermature morgagnian cataract.Results
The mean corrected distance visual acuity (CDVA) improved from 2.62 ± 0.25 Log MAR to 0.35 ± 0.28 Log MAR at 3 months postoperatively (P = 0.00008). Total nine out of 11 patients gained CDVA of 20/40 or better at 3 months postoperatively. No intraoperative complications such as posterior capsular rupture, zonular dialysis, iris trauma, vitreous loss were noted. The mean endothelial cell loss was 148.82 ± 41.52 cells/mm2 after 3 months of surgery.Conclusion
The main culprit for intraoperative complications during phacoemulsification in a morgagnian cataract is the vulnerable capsular bag. Following insertion of a CTR after capsulorhexis, the bag becomes stable and the subsequent steps of the surgery become uneventful, thereby, preventing any further complications.
