Intraocular lens calculation for aspheric intraocular lenses.
PURPOSE To evaluate the possible benefits of biometry and ray-tracing intraocular lens (IOL) calculation for aspheric aberration-correcting IOLs. SETTING Private eye clinic in Germany. DESIGN Retrospective consecutive case series. METHODS Eyes with 3 different aberration-correcting IOLs were reviewed. Before surgery, the axial length, corneal thickness, anterior chamber depth, crystalline...
متن کاملToric phakic intraocular lens: European multicenter study.
OBJECTIVE To evaluate safety, efficacy, predictability, stability, complications, and patient satisfaction after implantation of Artisan toric phakic intraocular lenses (TPIOLs) for the correction of myopia or hyperopia with astigmatism. DESIGN Prospective, nonrandomized, comparative (self-controlled) multicenter trial. PARTICIPANTS Seventy eyes of 53 patients (mean, 35 years; range, 22-59 ...
متن کاملIOLMaster keratometry for the calculation of toric intraocular lens power and orientation
In the implantation of intraocular lenses (IOL) stringent requirements are made on achieving the refractive target. This necessitates the exact determination of the basic data needed for IOL power calculation – both the axial length and, in particular, the corneal power – and additionally the cylinder power and its axis in the case of a toric lens. This gives rise to the question, especially fo...
متن کاملComparison of visual outcomes after implantation of diffractive trifocal toric intraocular lens and a diffractive apodized bifocal toric intraocular lens.
PURPOSE The aim of this study was to compare a new diffractive trifocal toric lens with an apodized diffractive bifocal toric lens in terms of refractive and visual acuity (VA) outcomes, including low-contrast VA (LCVA), as well as the patient's visual function 3 months after implantation. PATIENTS AND METHODS This is a randomized prospective study involving bilateral implantation of a trifoc...
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...
