Abstract
Objective To observe the therapeutic effect of extracapsular cataract extraction of Ⅳ/Ⅴ grade sclerotic cataract with IOL implantation after glaucoma trabeculectomy through a small incisions.Methods Eighty-two cases(114 eyes)of Ⅳ/Ⅴ grade sclerotic cataract accepted cataract extraction through an anti-superciliary arch temporal corneal limbus lamellar scleral tunnel incision with IOL implantation after glaucoma trabeculectomy for more than half a year.Follow up 6-12 months.The postoperative vision,IOP,filtrate bleb and complications were observed.Results The postoperative vision were improved in 82 cases(114eyes) ,in which 34 eyes' (29.82%) vision ≥ 0.6,47 eyes' (41.23%) 0.4-0.6,27 eyes' (23.68%) 0.2-0.4,6 eyes'(5.26%) ≤0.2.The postoperative filtrate blebs were well-preserved and the pupils forming effective,41 of the pupils on the move,mydriasis and deformation were improved.The postoperative average IOP was(15.15 ±2.78)mm Hg(1 mm Hg = 0.133 KPa) ,and it was no statistically significant differences in pre-or post-operative intraocular pressure(t'= 0.21 ,P ＞ 0.05).There were 38 eyes with corneal edema and 3 eyes with uveitis after improved surgery.Conclusion This operative technique is effective to treat sclerotic cataract after glaucoma surgery.,which is simple and easy to promote.
