Official Title: Subfoveal Choroidal Thickness After Femtosecond Laser-assisted Cataract Surgery for Age-related Cataracts

Brief Summary: 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.

Detailed Summary: 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).

Current Primary Outcome: The change of subfoveal choroidal thickness [ Time Frame: baseline, at 1 day after surgery, 7 days after surgery, 1 month after surgery, and 3 months after surgery ]

The subfoveal choroidal thickness were measured at baseline and at 1 day, 7 days , 1 month , and 3 months postoperatively by spectral-domain optical coherence tomography.


Original Primary Outcome: Same as current

Current Secondary Outcome: The change of subfoveal retinal thickness [ Time Frame: baseline, at 1 day after surgery, 7 days after surgery, 1 month after surgery, and 3 months after surgery ]

The subfoveal retinal thickness were measured at baseline and at 1 day, 7 days , 1 month , and 3 months postoperatively by spectral-domain optical coherence tomography.


Original Secondary Outcome: Same as current
