Abstract Details

Purpose:

Analysis of clinical outcome obtained with a diffractive extented depth of focus IOL (Tecnis Symfony ©(J&J) implanted on eyes that have previously undergone refractive surgery (pIOL(phakic IOL), KR, PKR or LASIK).

Setting:

University Brest Hospital - Ophtalmologie - France

Methods:

A monocentric retrospective observational study (CHU Brest) between January 2015 and November 2018 that included 42 eyes from 21 patients who received this implant with a theoretical design of elongated focal zones and correction of chromatic aberrations. The refractive power was calculated using the K-1 method, correlated to Haigis suite formula. Postoperative evaluation included topography and visual acuity at the 3 main distances, questionnaire of life and collection of functional symptoms.

Results:

Of the 42 eyes, 16 had a history of RK, 4 of PRK, 6 of LASIK and 8 of pIOL and 8 combined corneal surgeries. Mean uncorrected visual acuity for distance, intermediate, and near was 0.69, 0.58, and 0.47  at the 3 month. Significantly better UCDVA was observed in the pIOL group than in the other subgroups. Only 13.6% of eyes requiring frequent eyeglass wear. 70% of patients reported no or mild photic phenomena. Patient satisfaction (median) scores for distance, intermediate and near vision were 8.0, 7.0 and 6.0 respectively. More than 90% of patients would recommend the same procedure.

Conclusions:

When more and more patients who have undergone refractive surgery require cataract removal, calculating the correct power of the intraocular implant is a real challenge, especially since the operated patient is demanding the maintenance of eyeglass independence. Faced with the pitfall of residual refractive error for a multifocal implant whose success depends on obtaining emmetropia, the EDOF concept seems attractive for these eyes reshaped by previous refractive surgery.
