A Comparison Of Porous Infusion Anterior Chambermaintainer And Ophthalmic Device Used In Phacoemulsification With Intraocular Lens Implantation On The Effect Of The Macular Central Fovea Thickness

Objective:To investigate the change of macular central fovea thickness in phacoemulsification with intraocular lens implantation by using continuous anterior chamber infusion with balanced salt solutions irrigated from the porous anterior chamber maintainer and ophthalmic viscoelastic device.Methods:One hundred and thirteen eyes of 110 patients of age-related cataracts undergoing phacoemulsification with intraocular lens implantation were included. Fifty-night eyes of 53 patients were randomly allocated into porous anterior chamber maintainer group and 54 eyes of 47 patients were randomly allocated into viscoelastic group. All patients underwent surgery by the same ophthalmologist. The main index was the thickness of macular central fovea. Secondary indicators were phacoemulsification time,phacoemulsification power,average operating time, accumulated energy complex parameter,best corrected visual acuity, and intraocular pressure.Results:Vision was significantly improved after surgery in both groups. There was no significant difference in best corrected visual acuity and intraocular pressure between the two groups before and after surgery. Macular central fovea thickness postoperative of two groups were higher than preoperative. There was significant difference in macular central fovea thickness between porous anterior chamber maintainer group and viscoelastic group at day 7 postoperative (193.24±16.88μm vs.201.14±20.88μm, P=0.02) and day 90 postoperative (205.02±15.69μm vs.209.66±18.93μm, P=0.04).There was no significant difference in macular central fovea thickness in different accumulated energy complex parameter at postoperative day 7,day30 and day 90.Conclusions:Macular central fovea retinal thickening can be found after phacoemulsification. The postoperative change of macular central fovea thickness in phacoemulsification with intraocular lens implantation by using continuous anterior chamber infusion with balanced salt solutions irrigated from the porous anterior chamber maintainer at day 7 postoperative,day 90 postoperative has less effect than viscoelastic device.
