First experience of implantation of extended depth of focus intraocular lenses in patients with glaucoma

Abstract

This study evaluates the effectiveness of implantation of extended depth of focus (EDOF) intraocular lenses (IOL) in patients with cataract and glaucoma. The study included 13 patients (16 eyes) who underwent implantation of the Lentis Comfort EDOF IOL (Teleon Surgical BV, Netherlands). Standard phacoemulsification cataract surgery with IOL implantation was performed in a planned manner after the hypotensive surgery stage in two eyes; a combined procedure was performed in 14 cases. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), near visual acuity, and intraocular pressure (IOP) measured with a Maklakov tonometer were assessed preoperatively, on the first day, and 3-6 months after surgery. Computer perimetry using the 30-2 program and spatial contrast sensitivity (SCS) assessment were also performed preoperatively and at the same follow-up time points. On the first day after surgery, UCVA was 0.53±0.65, BCVA was 0.85±0.45. Near UCVA (at 40 cm) was 0.5±0.14 on the first day after surgery and 0.56±0.18 at 3-6 months. According to computer perimetry data, retinal light sensitivity values increased in all patients in the long-term (-3.1±2.9 dB). SCS values increased for objects of all sizes compared to preoperative values. Implantation of EDOF IOL contributes to improved vision without reducing contrast sensitivity and retinal light sensitivity in patients with concomitant cataract and glaucoma.
