- Brief Summary
Phacoemulsification in eyes with a shallow anterior chamber (ACD \< 2.2mm) presents with problems of safe access to the cataract and increased vulnerability of the endothelium and a higher tendency of complications such as descemet's detachment and iris prolapse. A shallow anterior chamber is also responsible for the high incidence of glaucoma and postoperative complications after cataract surgery. Femtosecond assisted cataract surgery has made cataract surgery safer and more predictable. The effective phacoemulsification time and intra-operative manipulation is greatly reduced in FLACS. However phacoemulsification still remains the most widely performed cataract surgery around the world. Post-operative outcomes after phacoemulsification in patients having shallow anterior chamber have been extensively reported in literature over the years.
There is no head to head comparison in terms of intraoperative performance and post-operative outcomes between FLACS and phacoemulsification in eyes with shallow anterior chamber.
The aim is to compare the intra-operative performance and post-operative outcomes in eyes undergoing femtosecond laser assisted cataract surgery versus eyes undergoing phacoemulsification in eyes having shallow anterior chamber.
The study will bring an understanding on the question: Do patients undergoing Femtosecond laser assisted cataract surgery behave differently from those undergoing phacoemulsification?
- Detailed Description
Inclusion Criteria:
* Age-related cataract
* Shallow Anterior Chamber (\<2.5mm)
Exclusion Criteria:
-Ocular co-morbidity - corneal disorders, glaucoma, uveitis, previous ocular surgery
Surgical Technique :
* Standardized, Single Surgeon

The investigators will be evaluating the following parameters:
1. Primary outcome measure Corneal thickness on day 1, week 1 and 1 month (Change in corneal thickness of 15% from preop. will be considered significant).
2. Secondary outcome measures
* Corneal clarity -on day 1, week 1 and 1 month postoperatively
* Anterior chamber cells and flare (Hogan's criteria)
* Percentage change in endothelial cell density from preoperatively to 3 months postoperatively
* Unaided visual acuity (distance) on day 1 and 1 month.
* Best corrected distance visual acuity 1 month postoperatively
3. Other Observations :
1) Cumulative Dissipated Energy (CDE) 2) Surgical time 3) Fluid used 4) Descemets membrane detachment during surgery 5) Incidence of iris trauma 6) Any other intra-operative complications
