简要总结
Eyesight and quality of life improves in patients after refractive cataract surgery because this surgery treats myopia, hyperopia and presbyopia except astigmatism. In order to make a patient spectacle free Ophthalmologists use different methods during cataract surgery to minimize astigmatism.
详细描述
These methods includes limbal relaxing incisions (LRIs) or the insertion of toric IOLs, which are specifically intended to cancel out pre-existing astigmatism and astigmatic keratometry. This research will be conducted to see which method benefits more for treating preoperative astigmatism in eye.
