Abstract Details

Purpose:

Cataracts after angle closure glaucoma filtering surgery are challenging surgical cases which were always combined the hard nuclear, shallow of flat anterior chamber and lens subluxation. Some recent studies had shown that femtosecond laser–assisted cataract surgery (FLACS) significantly reduces the need for ultrasound energy, which may minimize mechanical trauma to the cornea and result in lower rates of CEC loss and corneal edema. In this study, we evaluate the efficacy of the FLACS for hard cataract after glaucoma filtering surgery.

Setting:

Wuhan Aier Eye Hospital / No. 481, Zhongshan Road, Wuhan, China.

Methods:

13 cases after glaucoma filtering surgery with hard cataracts of grades IV were prospectively comprised in this study. The steps of the FLACS include capsulotomy, lens fragmentation, and corneal incisions. After the FLACS, the 2.2mm coaxial micro-incision phacoemulsification and the implantation of intraocular lens were operated. The pre-operative best corrected visual acuity（BCVA） and post-operative uncorrected visual acuity（UCVA）, the cumulative dissipated energy (CDE) of the phacoemulsification , the parameters of the FLACS, include the docking time, the suction time and the laser time were recorded. The complications of the FLACS were analyzed.

Results:

92.3% (12/13) cases were successfully completed the FLACS. The docking time were (24.60±16.86）sec，the suction time were（101.27±20.09）sec，and the laser time were （23.30±5.55）sec. The most intraoperative complications of the FLACS include suction break (7.69%), pupillary constriction (15.38%)，anterior capsular tag （7.69%）. The CDE was 5.52±5.18. The UCVA was 0.22±0.16 (LogMAR) at 1 month postoperatively. The most postoperative complications were corneal edema (15.38%).

Conclusions:

Cataract after glaucoma filtering surgery was always combined the hard nuclear, shallow of flat anterior chamber and lens subluxation. The FLACS was effective and safe in hard cataract after glaucoma surgery, reducing CDE during lens fragmentation and providing precise capsulotomies.
