Abstract Details

Purpose:

To evaluate functional results and quality of vision after bilateral implantation of a bioanalogic, polyfocal intraocular lens WIOL-CF. The contrast sensitivity represents a robust indicator of functional vision. The contrast sensitivity function measured under varying conditions of luminance establishes the limits of visual perception. Contrast sensitivity examination is able to detect differences in functional vision when simple VA test cannot.

Setting:

Department of Ophthalmology, University Hospital Kralovske Vinohrady and 3rd Medical Faculty Prague, Czech Republic

Methods:

The WIOL-CF bioanalogic, polyfocal intraocular lens was implanted bilaterally after cataract extraction. The second surgery was performed 2 weeks after first successful implantation. Patients with any other ophthalmic pathology beside cataract were excluded. Contrast sensitivity under different lighting conditions were examined (CSV 1000) 3 months after surgery. 52 patients (104 eyes) in 3 months after surgery were examined and analysed.

Results:

Resulted contrast sensitivity measurements are in average above population norm for young people (20-55 years) in both photopic and mesopic light conditions.

Conclusions:

Excellent contrast sensitivity under photopic and mesopic light conditions and low level of severe and disturbing glare and halo are crucial for a good functional vision and high patient satisfaction and spectacle independence rates. FINANCIAL INTEREST: NONE
