To investigate whether femtosecond laser assisted cataract surgery (FLACS) is associated with a lower rate of posterior capsular opacification (PCO) compared to traditional phacoemulsification cataract surgery.
Retrospective, consecutive case series. Medical records were reviewed of all patients who had uncomplicated cataract surgery with standard intraocular lens placement performed by one surgeon at a single surgery center between 10/1/2012 and 9/30/2013 and had at least 3 months’ postoperative follow-up data available. Data collected include demographics, preoperative refraction, history of prior ocular surgeries, history of ocular trauma or uveitis, type of cataract, date of surgery, size of capsulorhexis, intraoperative complications, and date of PCO diagnosis. Subgroup analysis was performed based on the factors listed above. Statistical analysis was performed using a Fisher exact t-test.
The study included 73 eyes (44 patients) which had received FLACS and 100 eyes (60 patients) which had received traditional phacoemulsification cataract surgery. Mean patient age in each group was 69 years. Mean duration of postoperative follow-up was 160 days in the FLACS group and 177 days in the phacoemulsification group (p=0.11 Wilcoxon test). PCO was diagnosed in 31/73 (43%) eyes in the FLACS group compared to 60/100 (60%) eyes in the phacoemulsification group (p=0.02 chi-square test). Among eyes with cortical cataract preoperatively, the proportion of eyes in which PCO was diagnosed was lower in the FLACS group (37%) compared to the phacoemulsification group (67%) (p=0.05 chi-square test). Among eyes with nuclear sclerosis and among eyes with posterior subcapsular cataract preoperatively, there was no significant difference between the FLACS and phacoemulsification groups with respect to the proportion of eyes in which PCO was diagnosed.
FLACS may be associated with reduced rate of PCO formation compared to phacoemulsification and this reduction may be more prominent in eyes with cortical cataracts preoperatively. Larger prospective studies are warranted to investigate these associations further.
