Title

MANAGEMENT OF IRREGULAR ASTIGMATISM AFTER CORNEAL ULCER WITH RGP CONTACT LENS IN PATIENTS WITH HIGH MYOPIA

Abstract

Introduction: The use of RGP contact lenses is indicated for correcting refractive errors in cases of high myopia and irregular astigmatism due to changes in the corneal curvature. Case Report: A 30-years-old female came with complaints of redness, pain, glare, blurred vision, and yellow discharge and tearing on the left eye for 2 days. History of using Soft Contact Lens (SCL) since 10-years-old due to myopia. Visual Acuity of the right eye (VOD) with glasses was 6/12 and VA of the left eye (VOS) was 1/300. Patient was diagnosed with left eye corneal ulcer and was given levofloxacin eye drops, hydroxypropyl methylcellulosa eye drops, and vitamin C 1000 mg. After 3 days, the complaints were decreased but corneal ulcer in the left eye leaving scars, causing irregular corneal surface. Patients were advised to replace the contact lenses with RGP contact lenses. After the RGP fitting, the appropriate size was obtained in both eyes and the patient adapted well with VOD RGP 1.0 and VOS RGP 1.0 False. The patient felt helped by the RGP contact lens. Discussion: RGP was given because it helped to reduce the risk of bacterial infection. RGP has a higher oxygen transmissibility as well as maintain the shape of the corneal curvature to become more regular so it can be used for irregular astigmatism beside as optical device for correcting high myopia. Conclusion: RGP contact lens can be an option for irregular astigmatism after corneal ulcers due to the SCL use in patients with high myopia to provide good outcomes.
