ABSTRACT
PURPOSE: This study evaluates the effectiveness of implantation of extended depth of focus (EDOF) intraocular lenses (IOL) in patients with cataract and glaucoma. MATERIAL AND METHODS: 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. RESULTS: 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. CONCLUSION: Implantation of EDOF IOL contributes to improved vision without reducing contrast sensitivity and retinal light sensitivity in patients with concomitant cataract and glaucoma.

Secondary glaucoma is one of the main problems of rehabilitation of patients with traumatic damage of the iris. PURPOSE: This study analyzes the long-term results of rehabilitation of patients with posttraumatic aniridia and glaucoma. MATERIAL AND METHODS: The study included 310 patients (310 eyes) with posttraumatic aniridia who had artificial iris-lens diaphragm (ILD) MIOL-Raduzhka implanted in 2002-2022. Before ILD implantation, 61 patients (22.8%) had secondary glaucoma. Among them 35 patients (11.3%) underwent various modifications of glaucoma surgery. In 26 patients (8.6%), intraocular pressure (IOP) was compensated medically before ILD implantation. RESULTS: Until the third month after ILD implantation, there was a trend for IOP increase in some patients. Decompensation was noted in 8 (22.9%) out of 35 patients who had underwent glaucoma surgery. IOP decompensation was observed in 21 (80.8%) of 26 cases in patients with glaucoma compensated by drugs before ILD implantation. After ILD implantation, glaucoma appeared for the first time in 21 patients (6.8%) out of 310. In order to compensate IOP after ILD implantation, Ahmed valve implantation was performed most often - in 35 cases (70%) out of 50, deep sclerectomy - in 5 cases (10%), non-penetrating deep sclerectomy - in 4 cases (8%), micropulse transscleral laser cyclophotocoagulation (MP-TSCPC) - in 5 cases (10%), endoscopic cyclophotocoagulation (ECP) - in 1 case (2%). CONCLUSION: ILD implantation in patients with posttraumatic aniridia and secondary glaucoma should be performed with IOP compensated without hypotensive therapy and not earlier than 6-12 months after glaucoma surgery. The most optimal glaucoma surgery types in this group of patients are Ahmed valve implantation and MP-TSCPC.
