简要总结
Toric intraocular lenses (IOL) have become the choice to correct corneal astigmatism of 1D or more in cases undergoing cataract surgery. Intraoperative toric intraocular lens alignment were initially done using conventional manual marking methods. However, with a recently introduced digital marking system, toric intraocular lens can be aligned without preoperative manual marking.
The primary objective of this study is to measure difference in toric intraocular lens misalignment between intraoperative image guided system and conventional manual marking method.
