Abstract

To correct a high hyperopia and irregular astigmatism secondary to multiples refractive surgeries in a 45 years old female, radial incisions suture and intraocular (IOL) Acrysof Toric lens was performed. To correct the residual refractional error a pseudophakic toric supplementary IOL was implanted over the primary one.The initial visual acuity (VA) was LogMAR 0,9 and the final VA was LogMAR 0,3. The implant of IOL supplementary over a primary toric IOL appears to be a good option, increasing the visual [...]

Highlights

Eye glasses are not satisfactory for correction of hyperopia secondary to radial keratotomy (RK) because they do not correct irregular astigmatism or higher order aberrations[1]. Treating such high hyperopias is a challenge for refractive surgeons
The haptics have a posterior angulation of 10 degrees, increasing separation with the iris anteriorly and the primary intraocular lenses (IOLs) posteriorly and reducing the risk of interlenticular opacification[4]
Since in the case reported here the possibility to correct the refractive error was limited, and despite the fact that the patient had irregular astigmatism, implantation of a SulcoflexTM IOL seemed to be the safest and least traumatic option compared with other alternatives

Summary

INTRODUCTION

Eye glasses are not satisfactory for correction of hyperopia secondary to radial keratotomy (RK) because they do not correct irregular astigmatism or higher order aberrations[1] Treating such high hyperopias is a challenge for refractive surgeons. The haptics have a posterior angulation of 10 degrees, increasing separation with the iris anteriorly and the primary IOL posteriorly and reducing the risk of interlenticular opacification (a frequent complication of piggyback plano-convex IOLs, especially if both IOLs are in the capsular bag)(4) Even though it is primarily indicated for correction of spherical or cylindrical pseudophakic ametropias, or even pseudophakic presbyopia, it has been suggested preoperatively for surgical correction of high refractive errors, congenital cataract and corneal astigmatism, among others[2]. The outcome was satisfactory with improvement of refraction to +0.50 -0.75 145° and a LogMar VA of 0.3 after a 4month follow-up
