Abstract Details



Purpose:

To report a patient with superiorly located keratoconus resembling Pellucid Marginal Degeneration who underwent a corneal wedge resection and primary suturation before a consequent cataract surgery.

Setting:

Baskent University Faculty of Medicine, Department of Ophthalmology, Ankara, Turkey.

Methods:

Interventional case report.

Results:

A 75 years old man presented to our clinic with low vision in both eyes. His corrected visual acuity was hand motion in the right eye and 5/100 in the left eye. He had grade 3 nuclear sclerosis in the right eye. His fundus examination was normal. However, refraction, keratometry and biometry could not be measured in that eye due to a severely distorted cornea. Pentacam analyses showed a cone formation in the superior cornea resembling superior pellucid marginal degeneration. We performed a crescent like wedge resection on the superior quadrant and after primary suturation the cornea was left to develop a scar that would tighten the superior corneal quadrant. Our aim was to obtain keratometric and biometric measurements before the cataract surgery. After 6 weeks of follow up, we the corneal sutures were removed. There was a scar formation along the resection site and the patient's visual acuity in the right eye had increased to 20/100. We were able to measure the biometry, refraction and keratometry before cataract surgery and performed phacoemulsification and intraocular lens implantation without any complications. Patient's final visual acuity 4 weeks after cataract surgery was 20/50.

Conclusions:

Lamellar crescent wedge resection and primary suturation is an effective way of treating pellucid marginal degeneration. In this case, this procedure enabled us to obtain a keratometry measurement and perform a consequent cataract surgery. FINANCIAL INTEREST: NONE
