Small Pupil Size Effect On The Function Of Extended Depth Of Focus Intraocular Lenses With Central Aberrated Segment Versus Continuous Transitional Focus Technology.

To evaluate and compare postoperative visual function and patient satisfaction after implantation of extended depth of focus (EDOF) IOLs with central, higher-order aberration segment versus a continuous transitional focus technology in patients with a pupil size of less than 2.5mm.

Department of Ophthalmology, Hospital Quironsalud, Marbella.

A retrospective case series evaluation of 250 patients with implantation of extended depth of focus (EDOF) IOLs with central, higher-order aberration segment (Vivity and Luxsmart) (Group1) and continuous transitional focus technology (CTF)(Precizon Presbyopic) (Group2)  was done to determine patients’ visual function and satisfaction after implantation of these IOLs with a photopic pupil size of less than 2.5mm. Group 1 included 150 patients (60%), and Group 2 included 100 patients (40%).

IOL power selection had been aimed at emmetropia in both groups.  3 months after the IOL implantation, seven patients (2.8%) were found in the EDOF IOLs group (Group 1) with a mean myopic subjective refractive error of (-0.50 +/-0.25). 6 of these patients (2.4%) underwent laser treatment for the refractive myopic error and dissatisfaction with the uncorrected distance visual acuity. In the group of CTF IOLs (Group 2), ten patients (4%) were detected without any significant subjective refractive error (p<0.001).

 In patients with a photopic pupil size of less than 2.5mm, CTF IOLs result in less myopic shift and patient dissatisfaction than the IOLs group with a central, higher-order aberration segment. Precizon presbyopic IOLs with CTF technology seem to be less pupil dependent.
