Comparison of Corneal Incision Versus Toric Intraocular Lens Techniques Used in Cataract Surgery

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Both genders were included.
  • Patients having astigmatism was included. Patients having cataract was included.
  • Eyes having no other ocular pathology 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.
  • Participants with a history of eye surgery within the past year will be excluded.

Treatment and study plan

Corneal Incision

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

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 .

Primary outcomes

  1. 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.

  2. 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 .
