Rotational and centration stability of an aspheric intraocular lens with a simulated toric design

Rotational and Centration Stability of the Aspheric

Objective analysis of toric intraocular lens rotation and centration.

PURPOSE To assess the repeatability of an objective image-analysis technique to determine intraocular lens (IOL) rotation and centration. SETTING Six European ophthalmology clinics. METHODS Eyes with an Akreos AO aspheric IOL with orientation marks were imaged. A masked observer rated image quality. The axis of rotation was determined from a line bisecting the IOL orientation marks. This wa...

Rotational stability and visual quality in eyes with Rayner toric intraocular lens implantation.

PURPOSE To assess astigmatic reduction and rotational stability of Rayner T-flex toric intraocular lenses (IOL) (573T and 623T; Rayner Intraocular Lenses Ltd) in a series of cataract surgery patients with corneal astigmatism >1.50 diopters (D). METHODS This prospective, observational study included 27 eyes from 22 consecutive patients with pre-operative regular corneal astigmatism ≥1.50 D in ...

Long-Term Efficacy and Rotational Stability of AcrySof Toric Intraocular Lens Implantation in Cataract Surgery

PURPOSE To evaluate the long-term efficacy and rotational stability of the AcrySof toric intraocular lens (IOL) in correcting preoperative astigmatism in cataract patients. METHODS This prospective observational study included 30 eyes from 24 consecutive patients who underwent implantation of an AcrySof toric IOL with micro-coaxial cataract surgery between May 2008 and September 2008. Outcome...

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...
