Abstract Details

Purpose:

To evaluate the surgical outcomes of patients with Fuch's endothelial dystrophy and cataract undergoing femtosecond laser-assisted cataract surgery (FLACS).

Setting:

Retrospective case series in a tertiary eye centre (National University Hospital, Singapore)

Methods:

In this retrospective case series, patients with known Fuch's endothelial dystrophy and cataract undergoing FLACS using the Catalys Precision Laser System between July 2013 to July 2015 by 3 surgeons were reviewed. The parameters analysed included pre and post-surgery best-corrected visual acuity (BCVA), corneal changes, corneal thickness and endothelial cell density (ECC) using specular microscopy over 24 months.

Results:

There are a total of 27 eyes of 21 patients included in the study. The cataracts were of varying nuclear densities based on the LOCS III classification. The mean pre-surgery ECC is 1909.2 ± 542.9 cells/mm2. The mean post-FLACS ECC is 1816.5 ± 519.5 cells/mm2.The mean percentage of endothelial cell density loss is 4.8 ± 14.0%. The mean change in corneal thickness is 18 ± 29µm and the mean percentage change in corneal thickness is 3.4 ± 5.5%. At 3 months post FLACS, 26 out of 27 eyes had BCVA better than 6/12.

Conclusions:

The percentage of endothelial cell density loss in the caser series is low at 4.8%. There was also no statistical change in corneal thickness post FLACS. Previous studies reporting the outcomes of patients with FED who underwent phacoemulsification cataract surgery showed a mean loss of 13.5% in endothelial cell density. Our results suggest that FLACS may have a role in patients with Fuch's endothelial dystrophy in minimizing the amount of endothelial cell damage.
