Abstract Details

Purpose:

To determine whether patients having cataract surgery using Femtosecond laser-assisted lens fragmentation and anterior capsulotomy have less intraocular inflammtion and complications versus manual cataract surgery in a one day follow up.

Setting:

Single center, prospective, matched clinical study

Methods:

Subjects having cataract graded preoperatively via LOCS II System. All subjects underwent LENSAR laser assisted cataract surgery with anterior capsulotomy, lens fragmentation and corneal arcuates if needed. Conventional cataract surgery involved manual capsulorhexis. Both procedures were completed by standard ultrasound phacoemulsification and implantation of an intraocular lens. Main outcome measures: Effective phacoemulsification time (EPT), mean phaco energy, mean phaco time, cells and flare and corneal opacity one day post-operatively.

Results:

In the Conservative cataract surgery GROUP CAT-1-2 mean EPT was 1, 50 (SD=0,67) seconds. The APT mean 14, 89 (SD=5,63) seconds. The grading of inflammation medians: CELL x̃=1, FOLDS x̃=0,5, EDEMA x̃=0,5; FLACS GROUP-1-2 the EPT was 1,07 (SD=0,62) seconds, the APT 10,8 (SD=4,05) seconds. Medians: CELL x̃=0,5, FOLDS x̃=0,5, EDEMA x̃=0,0. In the CCS GROUP CAT-3-4 the EPT was 2,07 (SD=0,79) seconds, the APT 17,08 (SD=5,17) seconds. Medians: CELL x̃=1, FOLDS x̃=1 and in EDEMA x̃=0,75. In the FLACS GROUP-3-4 EPT was 1,76 (SD=0,71) and APT 14,78 (SD=5,9) seconds. CELL x̃=1, FOLDS x̃=1, EDEMA x̃=0,5

Conclusions:

Patients undergoing Femtosecond laser-assisted cataract surgery do not have significantly less inflammatory signs than patients having conservative cataract surgery. However, the amount of energy used during phacoemulsification was significantly reduced in the group of patients that underwent Femtosecond laser-assisted cataract surgery.
