UNLABELLED: At present, implantation of multifocal IOLs in patients with primary open-angle glaucoma (POAG) remains questionable.
PURPOSE: To comparatively analyze the clinical and functional effectiveness of bifocal IOLs implanted during combined cataract and glaucoma surgery.
MATERIAL AND METHODS: The prospective study included 41 patients (75 eyes) with presbyopia and POAG who underwent one-stage cataract phacoemulsification with implantation of a multifocal IOL and non-penetrating deep sclerectomy (NPDS) with lens capsule. Group 1 included 24 patients (44 eyes) with implantation of diffractive-refractive IOL. Group 2 consisted of 17 patients (31 eyes) who were implanted aspheric diffractive IOL with asymmetric optics.
RESULTS: Mean IOP in both groups was 18.1±2.9 mmHg, and the difference with the preoperative parameters (26.1±2.8) was statistically significant (p<0.05). On average, the patients received 1.3±0.5 antihypertensive drugs compared to 2.4±0.61 before surgery (0.05<p<0.1). Near uncorrected visual acuity (nUCVA) in group 1 was 0.51±0.12 (p=0.009), in group 2 - 0.53±0.1 (p=0.01). Distant uncorrected visual acuity (dUCVA) was 0.59±0.09 (p=0.043) In group 1, and 0.57±0.04 (p=0.021) in group 2. Near best corrected visual acuity (nBCVA) in group 1 was 0.64±0.07, and 0.64±0.09 in group 2. In all studied groups postoperative nBCVA after 1 year of observation was significantly higher than before the surgery (p=0.006 and p=0.009 respectively).
CONCLUSION: The main study goal (dBCVA=1.0 at 1 year after surgery) was achieved in 31.8% of cases in group 1 and in 29.1% of cases in group 2 (p>0.1). Implantation of multifocal IOLs in combination cataract and glaucoma surgery is a safe and effective surgical intervention for the described group of patients.
