Abstract Details

Purpose:

There is very limited data about the safety and efficacy of Femtosecond (FS) laser platforms to create anterior capsulotomy in white intumescent cataracts. The aim of this study is to compare the efficacy and safety of FS laser capsulotomy between mature and nonmature cataracts.

Setting:

Kaskaloglu Eye Hospital, Izmir, Turkey

Methods:

A total of 133 eyes of 97 patients were enrolled in this study. The Lens Opacities Classification System III grading score (LOCS) was used in order to classify patients into two main groups according to the type of the cataract: mature and non-mature. The LenSx laser system (version 2.20 software, Laser SoftFit TM, Alcon Labs Inc, Fort Worth, TX) was used to perform all the femtosecond cataract procedures. Intraoperative measurements included the attachment of the anterior capsule (tag, incomplete capsulotomy, free floating capsulotomy), anterior capsule tears, and posterior capsule ruptures.

Results:

There were 64 (%66) males and 33 (%34) females. The mean age was 69.2±10 years. There were 50 eyes in group I (mature cataract) and 83 eyes in group II (grade I-IV cataracts). In 20 out of 133 eyes (15%) capsule tags occurred. Of these 20 eyes, 12 were in group I, and 8 were group II. The number in tag occurrence was statistically higher in group I when compared to group II (p=0.011). Incomplete CCC was significantly higher in group I when compared to group II (p<0.0001). Free CCC was present in 36 out of 50 eyes (72%) in group I and 75 out of 83 eyes (90%) in group II (p=0.03).

Conclusions:

The grade of cataract significantly increased the number of capsule problems in FS laser capsulotomy. In challenging mature cataract cases, the surgeon should be aware of limitations of FS laser capsulotomy in order to prevent capsule related complications.
