Al-Azhar International Medical Journal
Background: Conjunctival tissue encroaches triangularly into the cornea to form pterygium. In a progressive pterygium, it may be red, thick, and fleshy, while in an atrophic pterygium, it may be pale, thin, and membranous. The precision of the estimated intraocular lens (IOL) power can be affected by significant corneal astigmatism brought on by a big pterygium.
Objective: To detect the relationship between pterygium size and its impact on IOL power calculation. That is for accurate calculation of IOL power before cataract surgery.
Patients and Methods: A prospective, non-randomized controlled clinical trail was performed at the ophthalmology department of Al-Zahraa University …
