Observation on the effect of intraocular lens implantation in single-haptic ciliary sulcus with one needle and double suture fixation

Abstract

Objective To study the safety and efficacy of intraocular lens implantation in single-haptic ciliary sulcus with one needle and double suture fixation.Methods For 26 patients (26 eyes),the intraocular lens were implanted into single-haptic ciliary sulcus with one needle and double suture fixation.In the operation,the scleral flap was made under corneoscleral limbus( size of 3 mm × 3 mm)and the sutured needle under scleral flap with two polypropylene long suture was as fixation point,then the needle was to be inserted vertically from sclera and with drawn the needle 3 mm from the optical zones of cornea;extracted the polypropylene suture via cataract incision after cutting off long suture and ligated the suture at the same haptics of intraocular lens,the other haptics of intraocular lens was implanted into the residual posterior capsule and made the intraocular lens in the center.The postoperative vision,position of intraocular lens,complications and drug usage were observed,the patients were followed-up from one to six months.Results By one week after operation,the postoperative vision was ≥0.5 in 19 eyes(73.08% ) and between 0.1 and 0.4 in 7 eyes(26.92% ).the position of intraocular lens was normal in 24 cases(24 eyes)and lens decentration in 2 cases(2 eyes).Conclusion The intraocular lens implantation in single-haptic ciliary sulcus with one needle and double suture fixation is simple,safety and less complication,and the effect is good.
