A new one-piece bioanalogic extended-depth-of-focus (EDOF) intraocular lens (IOL), the Wichterle-Continuous Focus IOL (WIOL-CF, Medicem International CR), without haptics may be an excellent option for patients desiring correction of presbyopia after cataract surgery.
A multicenter clinical trial reported excellent visual outcomes and high patient satisfaction with bilateral implantation of this IOL after cataract surgery, according to H. Burkhard Dick, MD, PhD.
This IOL boasts a number of characteristics, i.e., negative spherical aberrations providing its smooth hyperbolic curve, an infinite number of focal points that extend the depth of focus, refractive power that is maximal in the center that continuously decreases without steps to the periphery, and a large optic that ensures maximal light in the eye, he pointed out.
The IOL powers range from +15 to +30 diopters (D) in 0.5-D steps; the overall and optic diameters are 8.6 and 8.9 mm; the lens thicknesses range from 0.8 to 1.7 mm, the refractive index is 1.428 ± 0.003, and the water content is 42 ± 2%, Dr. Dick recounted. He is Professor of Ophthalmology and Chairman, Ruhr University Eye Hospital, Bochum, Germany.
