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 Intraocular Lenses in Cataract Surgery
In modern cataract surgery, spectacle freedom is becoming more and more important. Emmetropia can be achieved for patients with myopic or hyperopic refractive errors by selecting the appropriate spherical lens power. However, approximately 20% of patients who undergo cataract surgery have 1.25 diopters (D) of corneal astigmatism or more. (FerrerBlasco, Montes-Mico et al. 2009; Hoffmann and Hutz...
متن کاملRepositioning technique and rate for toric intraocular lenses.
I previously reported the excellent rotational stability of the AcrySof toric intraocular lens (IOL) (Alcon, Inc.) in a consecutive series of my first 100 cases. Ninety percent and 99% of the IOLs were aligned within 5 degrees and 10 degrees of the intended axis, respectively, and no IOL required surgical repositioning. I compared the results in this series with those in my retrospective series...
متن کاملToric Intraocular Lenses for the Correction of Astigmatism
The ideal procedure for the correction of astigmatism should provide: precise and accurate adjustment, safety, predictable outcome, lasting effect and simplicity with an acceptable price. Conventional methods for solving problems such as glasses and/or contact lenses at the present time often do not meet the needs of patients. Whether it is the objective or subjective reasons for a large number...
متن کاملComparison Between Digital and Manual Marking for Toric Intraocular Lenses
To compare the clinical outcome of digital and manual marking for toric intraocular lens (IOL) alignment. This is a prospective clinical study that included 60 eyes of 60 patients undergoing cataract surgery with coexisting corneal astigmatism more than 1 diopter (D). The eyes were randomly assigned to either digital image guidance using VERION digital marker (Alcon Laboratories, Ft. Worth, TX)...
