Comparison of High-Order Aberrations and Endothelial Cell Loss Between Standard Phacoemulsification and Femtosecond Laser-Assisted Cataract Surgery
Narrative Responses:
Purpose
To compare HOA (Total Aberrations, Mean Root Square, Coma and Tilt) and ECL after Standard Phacoemulsification and Femtosecond Laser Cataract Surgery.
Methods
We did a prospective study that included 50 eyes of 32 patients who underwent cataract surgery with standard phacoemulsification (group 1) using the Infiniti System (Alcon Laboratories) and 50 eyes of 38 patients who underwent laser cataract surgery (group 2) with the LenSx Femtosecond Laser (Alcon Laboratories) . Both groups had similar demographic characteristics preoperatively. All eyes had a complete ophthalmic examination before and 3 months after surgery. We evaluated Endothelial Cell Count, HOA, RMS, Coma and Tilt in both groups. We did statistical analysis to compare results between groups.
Results
Three months after surgery, mean total aberrations in group 1 and group 2 was 0.92±0.74 and 0.8±0.62 respectively. Mean Coma in group 1 and 2 was 0.13±0.16 and 0.18±0.12 respectively. Mean Tilt in group 1 and 2 was 0.25±0.23 and 0.30±0.39 respectively. Mean RMS in group 1 and 2 was 0.49±0.46 and 0.41±0.25 respectively. There was no statistically significant difference between groups 1 and 2 in HOA, Coma, Tilt and RMS. Mean Endothelial Cell Lost in group 1 and group 2 was 7.1±3.5% and 9.3±4.1% respectively, with no statistically significant difference.
Conclusion
We did not find differences between standard phacoemulsification and femtosecond laser cataract surgery in terms of HOA and endothelial cell lost. Further investigation is necessary to evaluate these results with longer follow-up in a bigger sample size.
