Purpose
To compare the architecture of 2.2 mm clear corneal incision constructed using femtosecond laser vs. manually using a stainless steel keratome in uncomplicated phacoemulsification
Setting
Aravind Eye Hospital , Pondicherry
Methods
All consenting adults with age related cataract without coexistent ocular pathology were assigned to either femtosecond assisted cataract surgery (FLACS) or conventional phacoemulsification based on their choice. The wound architecture was assessed by a masked observer using the anterior segment optical coherence tomography including incision configuration, localized corneal thickness, epithelial and endothelial misalignment and gaping and localized descemet’s membrane detachment (DMD) at postoperative day 1, 7 and 30.
Results
A triplanar incision was seen in 100% eyes with FLACS vs. 59% in phaco (p<0.001). The localized corneal thickness lower in FLACS at 1 week (815+15 vs. 833+14, p<0.001) but this was not seen at 1 month. There was significantly lower endothelial misalignment in FLACS at 1 day and 1 week difference reduced at 1 month. Similar trends were seen with endothelial gaping (68% vs. 98% on day 1, p<0.001 and 36% vs. 57% at 1 month, p=0.09) and localized DMD (10% in FLACS vs. 38% in phacoemulsification at day 1, p<0.001), though there were no differences at 1 month.
Conclusions
Corneal incision with the femtosecond laser had better wound architecture with triplanar incisions and better configuration with lesser endothelial misalignment, gape and fewer eyes with transient DMD.
