Overview
Brief Summary
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.
Detailed Description
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.

Eligibility Criteria
Inclusion Criteria
- •Both genders were included.
- •Patients having astigmatism was included. Patients having cataract was included.

- •Patients having no history of corneal scar was included
Exclusion Criteria
- •Eyes having any ocular pathology will be excluded.
- •Patients with corneal suture will be excluded.
- •Those using contact lenses instead of spectacles for vision correction will be excluded.

Outcomes
Primary Outcomes
postoperative visual acuity
Time Frame: 12 Months
The postoperative visual acuity and refractive outcomes between patients undergoing cataract surgery with corneal incision and those with toric IOL implantation.
effectiveness of astigmatism correction
Time Frame: 12 months
Investigate the effectiveness of astigmatism correction achieved by both toric iol and corneal inscion technique and determine the degree of residual astigmatism in both groups after followups .
