Abstract Details


To compare refraction and visual acuity (VA) after toric posterior-chamber phakic intraocular lens implantation in keratoconic eyes versus non-keratoconic ones


Instituto de la Visión, Buenos Aires, Argentina


We retrospectively analyzed VA, sphere, cylinder and spherical equivalent (SE), and complications in 30 eyes with keratoconus (Group 1) and 35 eyes with non-keratoconic corneas (Group 2) after implantation of posterior chamber phakic IOLs (Visian ICL). Minimum follow-up was 1 year. Age was 36.9±10.3 (group 1) and 34.9±8.8 (group 2). Follow-up (months) was 29.5±18.5 (group 1) and 40.2±23.1 (group 2). In group 1, 16 eyes (43.3%) had corneal procedures performed at least 6 month prior to ICL implantation (13 were Corneal cross-linking only). According to Amsler-Krumeich classification, keratoconus grade was 2.4±0.9.


Preoperative SE and cylinder were -8.5±5.1 and -3.8±2.3D D (group 1), -10.7±3.6 and -1.6±1.4 in group 2, respectively. Postoperative SE and cylinder were -0.44±1.2 D and -0.9±1.7D (group 1), -0.6±1.0 and -0.48±0.5 in group 2, respectively (p > 0.1). Preoperative UCVA was less than 0.1 in all the cases, while BCVA was 0.5±0.2 (Group 1) and 0.76±0.2 (group 2). Postoperative UCVA was 0.65±0.2 (group 1) and 0.74±0.3 (group 2). Postoperative BCVA 0.80±0.2 and 0.95±0.1 (group 2). Student’s T test was >0.01. No complications were detected


Implantation of toric posterior-chamber phakic intraocular lens for treating high myopia and astigmatism in eyes with not advanced keratoconus is a procedure at least quite predictable, effective, and safe as in non-keratoconic eyes. Efficacy and Safety indexes were significantly higher in keratoconic eyes.
