“…In the present study, it demonstrated a greater frequency of cataract surgery in female participants, similar to many recently published works (8,10,14,15,16,17,18) . This analysis may be related to two factors: women's greater concern for their health, therefore seeking more medical care and the longevity of eldery women.…”

“…The preoperative corneal astigmatism, there was a tendency of lower values, with a mean of -2.19, similar to studies such as Ahmed et al (10) of -1.70, and Lee et al (18) , of -1.76. However, the study by Hoffmann et al (17) observed higher values of corneal astigmatism before surgery, -3.55.…”

“…All of these statistically significant findings seem to support the reasoning of worldwide literature (8,15,17,18,19) . Except the axis of astigmatism, which varies greatly between studies, as in Ahmed et al (10) , that preoperatively the trend was in favor of the rule and after phacoemulsification it became the majority against the rule.…”

0,86 (±2,89), já o componente cilíndrico médio foi de -1,53 (±1,09), com predomínio do eixo contra a regra (51,6%). A acuidade visual logarítmica (logMAR) pré-operatória média foi de 0,32 (±0,25). O componente esférico pós-operatório médio foi de -0,02 (±0,53). O sucesso cirúrgico foi obtido em 71 olhos (74,7%), havendo uma diminuição significativa (p<0,001) do componente cilín-drico médio e da acuidade visual logarítmica pós-operatórios, com valores respectivos de -0,61 (±0,55) e 0,08 (±0,14), permanecendo o eixo contra a regra (33,7%). Conclusão: As lentes tóricas mostraram-se seguras e reprodutíveis quanto aos resultados pós-operatórios, tornando-se uma opção importante para obtenção de excelência nos resultados refratométricos finais.

“…13,15 Acrylic material has a stronger tendency to adhere to the capsule than silicone. 10,11 The Rayner toric IOL is made of a hydrophilic acrylic copolymer, with the mean rotation reported to be 3.44 degrees (range 0 to 12 degrees) 4 months postoperatively. 3 Intraocular lens rotation may also occur as a result of capsular bag shrinkage from fibrosis, causing compression against the IOL haptics, although this is more often noted to occur late postoperatively.…”

We describe a surgical technique of transscleral suture fixation for recurrent rotation of a double-loop hydrophilic acrylic toric intraocular lens (IOL) in the capsular bag. Two 9-0 polypropylene sutures are placed in the proximal and distal angulations of 1 of the IOL haptics through the capsular bag. The clockwise and counterclockwise traction provided by these sutures prevents rotation of the IOL in either direction. This technique can be used in cases of spontaneous postoperative IOL rotation to achieve stabilization. In the case we describe, the IOL remained stable 11 months following transscleral suture fixation at the desired axis.

“…Toric IOL implantation can be an effective method for correcting corneal astigmatism in patients with vitreoretinal diseases and cataract. This is because toric IOLs show good rotational stability, even in vitrectomized eyes [2]. Cataract surgery with the implantation of toric IOL in stable keratoconus is a safe and effective procedure regarding keratometry stability, visual and refractive results [3–5].…”

Correction of irregular and induced regular corneal astigmatism with toric IOL after posterior segment surgery: a case series

et al. 2017

BackgroundToric intraocular lens (IOL) implantation can be an effective method for correcting corneal astigmatism in patients with vitreoretinal diseases and cataract. Our purpose is to report the outcome of toric IOL implantation in two cases - a patient with scleral-buckle-induced regular corneal astigmatism and a patient with keratoconus following pars plana vitrectomy. As far as we are aware, there are no reported cases of toric IOL implantation in a vitrectomized eye with keratoconus nor of toric IOL implantation in patients with scleral-buckle-induced regular corneal astigmatism.Case presentationTwo patients with myopia and high corneal astigmatism underwent cataract operation with toric IOL implantation after posterior segment surgery. Myopia and high astigmatism (>2.5 diopter) were caused by previous scleral buckling in one case and by keratoconus in the other case. Pre- and postoperative examinations during the follow-up of included uncorrected and spectacle corrected distance visual acuity (UCDVA/CDVA), automated kerato-refractometry (Topcon), Pentacam HR, IOL Master (Zeiss) axial length measurements and fundus optical coherence tomography (Zeiss). One year postoperatively, the UCDVA and CDVA were 20/25 and 20/20 in both cases, respectively. The absolute residual refractive astigmatism was 1.0 and 0.75 Diopters, respectively. The IOL rotation was within 3° in both eyes, therefore IOL repositioning was not necessary. Complications were not observed in our cases.ConclusionThese cases demonstrate that toric IOL implantation is a predictable and safe method for the correction of high corneal astigmatism in complicated cases with different origins. Irregular corneal astigmatism in keratoconus or scleral-buckle-induced regular astigmatisms can be equally well corrected with the use of toric IOL during cataract surgery. Previous scleral buckling or pars plana vitrectomy seem to have no impact on the success of the toric IOL implantation, even in keratoconus. IOL rotational stability and refractive predictability in patients with a previous vitreoretinal surgery can be as good as in uncomplicated cases.
