Purpose

To evaluate the defocus curve of an Enhanced Depth of Focus (EDoF) IOL in the range of +1 to -4 diopters (D).

Setting

All surgeries were performed at the Breyer-Kaymak-Klabe Eye Surgery and Premium Eyes in Düsseldorf, Germany, a member of the International Vision Correction Research Center (

IVCRC.net

), by a single surgeon (Breyer).

Methods

This ongoing prospective study includes 20 eyes from 10 patients who underwent femtosecond laser cataract surgery (FLACS) and phacoemulsification with the implantation of an EDoF IOL (Eyecryl Sert, Biotech). Three-month postoperative follow-up included binocular uncorrected and monocular best-corrected defocus curve analysis in the range of +1 to -4 D. The target refraction was emmetropia in both eyes or emmetropia in the dominant eye and -1.5 D in the non-dominant eye (Düsseldorf Formula, blended vision). Patient satisfaction was assessed using the McAlinden Questionnaire regarding daily experiences, subjective optical quality, optical side effects, and quality of life.

Results

Initial results demonstrated good visual acuity. The new EDoF IOL allows for clear vision at distance, while intermediate vision is superior to that achieved with monofocal IOLs. Patient satisfaction results will be presented.

Conclusions

The Eyecryl Sert IOL, implanted in both eyes targeting emmetropia, presents a compelling alternative to monofocal IOLs for patients who desire the ability to work at computer distance without reading glasses. When implanted according to the Düsseldorf Formula in blended vision mode, patients were able to read books or newspapers without glasses. However, reading small print is often not feasible and should not be promised to patients.
