FUCHS ENDOTHELIAL CORNEAL DYSTROPHY: IS FEMTOSECOND LASER-ASSISTED CATARACT SURGERY THE RIGHT APPROACH?

Area of Science:

• Ophthalmology
• Surgical Technology
• Corneal Diseases

Background:

• Fuchs endothelial dystrophy poses risks during traditional cataract surgery due to endothelial sensitivity.
• Femtosecond laser-assisted cataract surgery (FLACS) utilizes lower energy, potentially reducing endothelial damage.
• FLACS automates key surgical steps like corneal incisions, capsulorhexis, and nucleus fragmentation.

Purpose of the Study:

• To evaluate the efficacy and safety of FLACS in patients diagnosed with Fuchs endothelial dystrophy.
• To assess the impact of FLACS on corneal health and visual outcomes in this patient group.

Main Methods:

• A prospective study involving 5 patients (6 eyes) undergoing FLACS using the LensX system.
• Analysis of pre- and post-operative corneal changes, including best-corrected visual acuity (BCVA) and pachymetry.
• Measurement of cumulative dissipated energy (CDE) during the procedure.

Main Results:

• Pre-operative BCVA ranged from 0.16-0.4, pachymetry from 450-590 µm, and endothelial cell counts from 789-2008 cells/mm².
• The average CDE was 4.58 seconds.
• All patients experienced improved BCVA post-surgery, with no instances of corneal decompensation observed.

Conclusions:

• FLACS is a safe and effective surgical option for managing cataracts in patients with Fuchs endothelial dystrophy.
• The procedure demonstrates a low risk of corneal decompensation, preserving endothelial function.
• FLACS offers a significant improvement in visual outcomes for this vulnerable patient population.
