About

To compare the effects of femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification surgery (CPS) on subfoveal choroidal thickness (SFCT) in age-related cataracts.

Full description

It is not clear whether femtosecond laser-assisted cataract surgery (FLACS) alters retinal and choroidal thickness. The goal of the present study was to determine the changes of retinal and choroidal thicknesses in patients who have undergone FLACS compared to patients who have undergone conventional phacoemulsification surgery (CPS).

Enrollment: 40 patients

Sex: All

Volunteers: No Healthy Volunteers

Inclusion criteria

• The cataract stages of the patients were between N2 and N4 according to the LOCS III.

Exclusion criteria

• eyes with histories of ocular surgery, trauma, and ocular diseases, including diabetic retinopathy, age-related macular degeneration (AMD), high myopia, psudoexfoliation, uveitis, retinal vein occlusion, and other inflammatory and vascular retinal disorders.
