“…21,22 Also, the preoperative and postoperative changes in endothelial cell density (cells/mm 2 ) were examined using a specular microscope (Topcon, SP-3000P). Serious postoperative complications recorded included the occurrence of retinal detachment, acute or chronic marked increase in intraocular pressure (IOP) of 30 mm Hg or higher, cystoid macular edema, vitreous hemorrhage, pupillary capture, and redislocation of the IOL.…”

Aim The purpose of this study was to compare the surgical outcomes of intraocular lens (IOL) refixation with intraocular lens exchange using perfluorocarbon liquid (PFCL) and fibrin glue-assisted sutureless scleral fixation surgery in patients with dislocation of the IOL. Methods Twenty-five eyes of 25 patients who underwent surgery for dislocated IOLs with PFCL and fibrin glue-assisted scleral fixation were studied; 13 eyes experienced IOL refixation (in-the-bag and out-of-the-bag), and 12 eyes experienced IOL exchange. Preoperative and postoperative clinical features from patient charts and 25 eyes with 46 months' follow-up information were reviewed and analyzed. Results At postoperative 6 months, best-corrected visual acuity (BCVA) and spherical equivalent of IOL refixation and exchange were significantly improved (P = 0.042, P = 0.001), and endothelial cell density was significantly decreased in the two groups with no significant difference between them. Surgically induced astigmatism of IOL refixation improved from 0.90 ± 0.47 to 0.61 ± 0.37 (P = 0.012), and IOL exchange improved from 1.17 ± 0.64 to 0.73 ± 0.37 (P = 0.037) at postoperative 6 months, with no significant difference between the two groups. Complications occurred in four eyes in the IOL refixation group and in three eyes in the IOL exchange group.Conclusion PFCL and fibrin glue-assisted IOL sutureless scleral refixation or exchanged fixation was an effective surgical treatment for IOL dislocation. Also, because postoperative BCVA, surgical outcomes, and complications did not differ significantly between IOL refixation and exchange surgery, if IOL exchange surgery is not indicated, IOL refixation surgical techniques should be considered.

“…Hence, patients with high degrees of myopia additionally benefit from the refractive correction that can result from cataract surgery, making lens exchange for purely refractive purposes an increasingly popular option, especially with modern micro-incisionional surgical techniques 8 . Toric IOLs are a major advance in pseudophakia, although its use is gaining popularity, the literature is poor when it comes to its use in keratoconus patients -an European article reports a foldable toric silicone IOL successfully employed in the management of marked regular corneal astigmatism caused by keratoconus 10 . To our knowledge, this is the first report on foldable hydrophobic acrylic toric IOL used for RLE in stage 2 keratoconus.…”

“…Once the anterior and posterior capsules fuse, IOL rotation is less likely to occur 9 . The SN60T5 AcrySof Toric IOL has shown excellent postoperative stability, with 95% of IOLs within 10 degrees of the intended axis of implantation 6 months after surgery 10 . When RLE is considered, keratoconus stability is important to maintain long-term refractive results, because progression would lead to increased corneal myopia and to reduce the risk for future keratoplasty, causing a hyperopic shift by means of a flatter cornea 3 .…”

This is a case report of a 45-year-old anisometropic woman with stage 2 keratoconus submitted to refractive lens exchange employing SN60T5 AcrySof Toric intraocluar lens on her left eye. Phacoemulsification followed by proper lens implantation was accomplished successfully. On postoperative period, favorable refractive and visual outcomes were obtained. The use of toric intraocular lenses may be an option in the refractive treatment of stage 2 keratoconus in selected cases.Keywords: Keratoconus; Lens implantation, intraocular; Anisometropi; Lens, crystalline/surgery; Case reports RESUMORelatamos o caso de uma senhora de 45 anos de idade, portadora de ceratocone grau 2 e consequente anisometropia, submetida à extração do cristalino transparente, e uso da lente intraocular modelo SN60T5 AcrySof Toric para o olho esquerdo. Facoemulsificação seguida pelo implante da lente intraocular tórica no olho esquerdo. No pós-operatório, resultados refracionais e visuais satisfatórios foram alcançados. O uso de lentes intraoculares tóricas pode se constituir em opção terapêutica para casos selecionados de ceratocone grau 2.

“…The expected amount of surgically induced astigmatism (SIA) has to be incorporated into the toric IOL power in order to select the most appropriate toric IOL model. (Hill 2008) However, the exact amount of SIA is difficult to predict and depends on several factors. The location of the incision is an important factor to consider, since corneal incisions lead to flattening of the incised meridian.…”

Expected effects of surgically induced astigmatism on AcrySof toric intraocular lens results

Abstract: With the AcrySof toric IOL, consideration of SIA from temporal or superior incisions resulted in statistically and clinically significantly lower anticipated residual astigmatism. The most important effect of including SIA appears to be more appropriate IOL selection.
