Positional accommodative intraocular lens power error induced by the estimation of the corneal power and the effective lens position
PURPOSE To evaluate the predictability of the refractive correction achieved with a positional accommodating intraocular lenses (IOL) and to develop a potential optimization of it by minimizing the error associated with the keratometric estimation of the corneal power and by developing a predictive formula for the effective lens position (ELP). MATERIALS AND METHODS Clinical data from 25 eyes...
متن کاملToric intraocular lens outcome using the manufacturer's prediction of corneal plane equivalent intraocular lens cylinder power.
OBJECTIVES To describe the refractive outcome of toric intraocular lens (IOL) implantation by comparing the postoperative refractive astigmatism with the preoperative keratometric astigmatism target. METHOD In a university department of a publicly funded hospital, 38 eyes of 29 patients underwent routine cataract surgery with insertion of a toric implant (SN60TT AcrySof Toric). Surgically ind...
متن کاملIntraocular lens power calculations in the triple procedure.
When a triple procedure is planned, calculation of the intraocular lens becomes a problem. Postoperative corneal power bears no relation to preoperative power, and the axial length of the globe also changes. A prospective study of 24 keratoplasties revealed a close relationship between postoperative corneal power and donor corneal power. Changes in axial length were found to be too small to pro...
متن کاملEffect of corneal aberrations on intraocular lens power calculations.
PURPOSE To use ray tracing to determine the influence of corneal aberrations on the prediction of the optimum intraocular lens (IOL) power for implantation in normal eyes and eyes with previous laser in situ keratomileusis (LASIK). SETTING Hospital Universitario Virgen de la Arrixaca, Murcia, Spain. DESIGN Case series. METHODS The optimum IOL power was calculated by ray tracing using a pa...
متن کاملPrediction of Refractive Outcome of Second Eye with Partial Adjustment of Intraocular Lens Power of the First Eye
Background and Objective: This study aimed at comparing the results of refractive cataract surgery in patients undergoing sequential surgeries in both eyes. Considering the preoperative refraction and final refraction of the first eye, it is possible to correct the refrative result of cataract surgery using the adjustment of the second eye intraocular lens (IOL) power. Materials and Methods: T...
