surgical selection of primary angle-closure glaucoma combined cataract

METHODS:In this study, 90 cases(96 eyes)with cararact combined angle-closure glaucoma were selected. Those were nonrandomly assigned into three groups by goniosynechia degree and disease coursing, and phacoemulsification with intraocular lens implant(Phaco+IOL), phacoemulsification with intraocular lens implant combined peripheral iridotomy(Phaco+IOL+PLI), and phacotrabeculectomy(Phacotrab+IOL)were non-randomly performed. Then preoperative and postoperative visual acuity, intraocular pressure(IOP), axial anterior chamber depth(AACD)and bleb were observed 1wk and 1mo.

RESULTS:In three surgical types of cararact combined angle-closure glaucoma,postoperative visions were evidently enhanced(P<0.05), while IOPs were evidently reduced(P<0.05). There was no significant difference among three groups-postoperative IOP respectively on 1wk and 1mo.

CONCLUSION: Phacoemulsification and combined operations by minimal invasive cornea treating glaucomaare safe. We perform Phaco+IOL in case of goniosynechia degree less than 90°, Phaco+IOL+PLI in case of goniosynechia degree between 90°～180°, Phacotrab+IOL in case of goniosynechia degree more than 180°.
