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.

Conditions

• Cataract Surgery

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Corneal Incision	Astigmatism will be assessed by objective and subjective refraction by using the Autorefrectometer and retinoscop.Autorefrectometer uses to acsess the refracive state of eye by which we measure the astigmatim in patients eyes .Then after ctaract surgry in the next followup we will again use autorefrectometer to take readings and these both will be compared on visits among patients undergoing two procedures.
OTHER	Toric Intraocular	Two cataract surgery techniques will be used .1 : Toric IOL lenses designed with a unique shape to help provide clear vision at all distances for individuals with astigmatism compared to give better results specially in astigmatic patients.2: Corneal Inscion is which eye surgeon makes a very small opening on the eye, next to the outer corner. to remove the catract during surgry .
