- Primary Outcome Measures
Name Time Method A) Changes in IOP and wound structure immediately after cataract surrgery 1) Longitudinal changes in IOP using rebound tonometer after cataract surgery preoperatively, at the conclusion of surgery; and at 15, 30, 60, and 120 minutes, and 24 hours postoperatively. 2) Seidel test at 30 minutes postoperatively 3) Wound structure at 30 minutes after surgery using the anterior segment-optical coherence tomography (AS-OCT) B) Changes in corneal astigmatism and shape preoperatively and at 2, 14, 30, and 60 days postoperatively 4) Corneal astigmatism and surgically induced astigmatism determined using keratometer 5) Corneal shape change determined using corneal topography 5-1) Averaged difference map 5-2) Irregular corneal astigmatism determined by Fourier analysis
- Secondary Outcome Measures
Name Time Method 6) Corneal endothelial cell counts and central corneal thickness 7) Visual acuity 8) Refractive status (spherical power, refractive cylinder, manifest spherical equivalent power)
