Visual Performance After RESTOR Implantation

2014-07-23 21:10:41 | BioPortfolio


The purpose of this study is to evaluate the distance, intermediate, and near vision after aspheric multifocal diffractive AcrySof® ReSTOR SN6AD1 intraocular lens (IOL) implantation.


To evaluate distance, intermediate, and near vision after aspheric multifocal diffractive AcrySof® ReSTOR SN6AD1 intraocular lens (IOL) implantation.

Prospective study of 50 patients with cataract that had phacoemulsification and AcrySof® ReSTOR IOL implantation. Uncorrected distance vision acuity (UDVA), corrected distance visual acuity (CDVA), distance-corrected near visual acuity (DCNVA), and distance-corrected intermediate visual acuity (DCIVA) were measured postoperatively. A patient-satisfaction and visual phenomena questionnaire was administered at the end of the study.

Medical and Biotech [MESH] Definitions

Deviations from the average or standard indices of refraction of the eye through its dioptric or refractive apparatus.

A procedure to surgically correct REFRACTIVE ERRORS by cutting radial slits into the CORNEA to change its refractive properties.

Surgical procedures employed to correct REFRACTIVE ERRORS such as MYOPIA; HYPEROPIA; or ASTIGMATISM. These may involve altering the curvature of the CORNEA; removal or replacement of the CRYSTALLINE LENS; or modification of the SCLERA to change the axial length of the eye.

Instruments for RETINOSCOPY that determines the refractive state of the EYE, such as the degree of NEARSIGHTEDNESS; FARSIGHTEDNESS; or ASTIGMATISM. In principle, a retinoscope provides a light source to illuminate the RETINA, and then locates the aerial image of the retina in space to obtain an index of the refractive quality of the patient's lens system.

Systematic identification of a population's needs or the assessment of individuals to determine the proper level of services needed.
