Purpose

To evaluate visual otucomes and refractive prediction accuracy following implantation of a non-diffractive extended depth of focus (EDOF) intraocular lens (IOL) in eyes that have undergone prior laser assisted in situ keratomileusis (LASIK) for myopia

Setting

 Raghudeep eye Hospital, Jaipur, India

Methods

Prospective interventional case series in eyes that have undergone myopic LASIK and scheduled for cataract surgery. A non-diffractive, wavefront shaping EDOF IOL was implanted. IOL power was calculated based on the Barrett post refractive IOL and ASCRS post refractive IOL calculator. 3 months postoperatively, unaided and corrected distance, near (40cm) and intermediate (60cm) visual acuity (UDVA, UIVA, UNVA, CDVA, CIVA, CNVA), manifest refraction and prediction error of refraction were evaluated. Patient’s subjective satisfaction was assessed using the McAlinden questionnaire.

Results

12 eyes (9 patients) were included. Mean age at surgery was 57.7 years. Mini-monovision was targeted in 2 patients with bilateral cataracts. 3 months postoperatively, mean UDVA was 0.15 + 0.18 (standard deviation), UIVA was 0.16 + 0.06, UNVA was 0.24 + 0.0  LogMAR units. CDVA, CIVA and CNVA were 0 LogMAR. No patient had any symptoms of dysphotopsia.

Conclusions

The non-diffractive wavefront shaping EDOF IOL gives good unaided visual acuity with a functional range of intermediate and near vision without additional dysphotopic phenomena. There is a tendency for slight myopic outcome. This IOL provides a feasible option for presbyopia correction in post myopic LASIK eyes
