Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Corneal Incision

Group Type EXPERIMENTAL

Corneal Incision

Intervention Type DIAGNOSTIC_TEST

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.

Toric Intraocular

Group Type ACTIVE_COMPARATOR

Toric Intraocular

Intervention Type OTHER

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 .
