Effect of Intraocular Lens Biomaterials on the Treatment of Primary Angle Closure Glaucoma

Abstract

To explore the effect of phacoemulsification along with intraocular lens (IOL) implantation on the treatment of primary angle closure glaucoma (PACG), a total of 50 patients (54 eyes) with PCG who had undergone surgery were selected as the research objects, in which, there were 16 eyes with the acute PACG in pre-clinical stage, 20 eyes with acute PACG during acute attack, and 18 eyes with chronic PACG, and all patients received phacoemulsification along with IOL implantation therapy. The patient’s best corrected visual acuity, anterior chamber (AC), anterior depth, intraocular pressure (IOP), visual field, and fundus conditions were measured during the operation, after the operation, and during the follow-up period. The postoperative visual acuity of the patients with three types of PACG was greatly corrected, in which 30 eyes had corrected visual acuity above 0.5, and there were statistically significant differences (SSDs) (P < 0.05); angle closure of 54 eyes had different degrees of improvement, the opening degree of the acute angle closure is better than that of the chronic angle closure, and there were SSDs (P < 0.05); each of 54 eyes showed different degrees of deepening in the central AC, and there were SSDs (P < 0.05); postoperative IOP decreased greatly in all 54 eyes, and there were SSDs (P < 0.05). In conclusion, the IOL implantation based on phacoemulsification can effectively treat the PACG, at the same time reduce IOP, promote angle opening, enhance vision field of the patients, and ultimately achieve the purpose of improving surgical success.
