Clinical Trial: Effect of Posterior Corneal Toricity on Refractive Outcome of Pseudophakia
Study Status: Completed
Recruit Status: Unknown status
Study Type: Interventional
Official Title: Effect of Posterior Corneal Toricity on Refractive Outcome of Pseudophakia
Brief Summary:
This study is to evaluate the necessity of considering posterior corneal toricity on refractive outcome of patients with cataracts and corneal astigmatism after implantation of intraocular lenses.
This is determined by comparing total corneal and refractive astigmatism,and by comparing the expected refractive result with actual refractive astigmatism postoperatively,using total corneal and anterior corneal astigmatism to calculate respectively.
