Abstract:AIM: To evaluate the methods and effects of secondary intraocular lens implantation based on proliferative membrane in anterior segment reconstruction.
METHODS: Totally 156 eyes with penetrating injury had varying degrees of anterior segment disorders which had secondary intraocular lens implantation based on proliferative membrane to anterior segment reconstruction. Including partial penetrating keratoplasty, front-adhesion release, iris root suture, post-adhesion release, pupillary plasty, hole making in pupil area proliferative membrane and secondary intraocular lens implantation based on proliferative membrane. All patients were followed up 3-18mo.
RESULTS: The surgeries were successful in all patients. The corrected visual acuity of 123 eyes(78.8%)were ≥0.5, 17 eyes(10.9%)were ≥0.8 and 33 eyes(21.2%)were ≤0.4. Postoperative intraocular lens position was 133 eyes(85.3%), intraocular lens slightly off the center of 23 eyes(14.7%). Anterior chamber hemorrhage occurred in 8 eyes, 6 of them were recovered by conservative treatment and the blood membrane in another 2 eyes were sucked out through primary incision, and 5 cases of corneal plaque dense in the center of the cornea are partially penetrating keratoplasty. After 2mo, a rejection reaction occurs, which is cured by conservative treatment. All patients had slight postoperative inflammation and without severe long-term complications.
CONCLUSION: Reconstruction of the anterior segment of the eye, proliferative membrane can support the intraocular lens at the pre-implantation of the intraocular lens, without the need for suture fixation, thus avoiding various complications due to sutures.
