Abstract
Purpose :
To assess the safety and efficacy of femtosecond laser-assisted cataract surgery (FLACS) in eyes with angle-closure glaucoma.
Methods :
Clinical records of 96 consecutive eyes of angle-closure glaucoma patients who underwent FLACS using four femtosecond lasers (FEMTO LDV Z8, Ziemer; LenSx, Alcon; Catalys Precision Laser System, Johnson & Johnson; LensAR, LensAR) and a phaco machine (Centurion Vision System, Alcon) were reviewed. For each laser platform, the completion rates of anterior capsulotomy, the incidence of posterior capsule rupture, and the number of attempts to achieve secure docking between the cornea and laser system were recorded. Uncorrected visual acuitiy (UCVA) and best-corrected visual acuity (BCVA), intraocular pressure (IOPs), corneal endothelial cell counts, and anterior chamber depth (ACD) were evaluated preoperatively and up to 1 year postoperatively.
Results :
The anterior capsulotomy was successfully completed in 95 eyes (98.96%) and the posterior lens capsule only ruptured in 2 eyes (2.08%). Difficulties in docking between the cornea and laser system were experienced due to narrow palpebral spaces in 8 eyes (8.33%), but no canthotomy was required for any of the eyes (0.00%). After FLACS, the IOPs were significantly reduced and ACD became deeper. Corneal endothelial cell counts were preserved. In addition, postoperative UCVA and BCVA were favorable up to 1 year postoperatively.
Conclusions :
FLACS was safe and effective even in eyes with angle-closure glaucoma. Further improvements in docking are required for small eyes with narrow palpebral spaces which are a frequent characteristic of eyes with angle-closure glaucoma.
