Implantation of a Multifocal Toric Intraocular Lens after Radial Keratotomy and Cross-Linking with Hyperopia and Astigmatism Residues: A Case Report
Radial keratotomy is a refractive surgical technique, widely used in the 80s and early 90s to correct myopia and astigmatism, but now overcome by more recent laser techniques. Important consequences, often in patients with more than 45 years of age, are progressive hyperopic shift and/or an increase in corneal astigmatism, whose main cause seems to be an increase in the curvature radius of the ...
متن کاملSuccessful toric intraocular lens implantation in a patient with induced cataract and astigmatism after posterior chamber toric phakic intraocular lens implantation: a case report
INTRODUCTION We report the case of a patient in whom simultaneous toric phakic intraocular lens removal and phacoemulsification with toric intraocular lens implantation were beneficial for reducing pre-existing astigmatism and acquiring good visual outcomes in eyes with implantable collamer lens-induced cataract and astigmatism. CASE PRESENTATION A 53-year-old woman had undergone toric implan...
متن کاملCorrection of High Astigmatism after Penetrating Keratoplasty with Toric Multifocal Intraocular Lens Implantation
After penetrating keratoplasty (PK), high astigmatism is often induced, being frequently about 4-6 dpt. According to the entity and typology of astigmatism, different methods of correction can be used. Selective suture removal, relaxing incisions, wedge resections, compression sutures, photorefractive keratectomy, and laser-assisted in situ keratomileusis can reduce corneal astigmatism and amet...
متن کاملVisual outcomes following implantation of a multifocal toric intraocular lens in patients with corneal astigmatism
METHODS: In this consecutive case series, patients underwent phacoemulsification and bilateral or unilateral IOL implantation with the M-flex T IOL (Rayner Intraocular Lenses Ltd.). All underwent refractive assessment and corneal topography preoperatively and postoperatively. Outcome measures included uncorrected distance VA, spherical and cylindrical refraction, and spherical equivalent (SE) (...
متن کاملArtisan iris-fixated toric phakic and aphakic intraocular lens implantation for the correction of astigmatic refractive error after radial keratotomy.
We report 2 patients who had radial keratotomy (RK) to correct myopia. The first patient developed a postoperative hyperopic shift and cataract. Nine years post RK, she had intracapsular cataract extraction and implantation of an Artisan aphakic intraocular lens (IOL). Twenty years post RK, hyperopia and astigmatism progressed to +7.0 -5.75 x 100 with a best corrected visual acuity (BCVA) of 20...
