ABSTRACT

AIM: To evaluate the clinical effects of secondary suspensory foldable intraocular lens ( IOL ) implanted in aphakia eyes after vitrectomy.? METHODS: The clinical data were retrospectively analyzed in 25 eyes of 25 patients treated with secondary suspensory intraocular lens implantation after vitrectomy. The surgery was performed through a incision 2. 4mm away from corneal edge, followed by solarometer positioning 800 and 200, and foldable intraocular lens was loaded and implanted by an injector, after that suspension line knot of lens was made, which length was equal to the distance between the loops of intraocular lens. The intraocular lens was fixed to sclera by a "W"shaped suspension suture. The patients were followed up for 3 ～ 26mo postoperatively, and visual acuity, intraocular pressure, cornea, anterior chamber reaction, intraocular lens position, fundus were observed.? RESULTS: All patients received preoperatively best corrected visual acuity at 1wk after surgery, and the refractive condition was within ± 1. 5 DC. The intraocular pressure was all normal. The number of corneal endothelial cells ( n/mm2 ) was 2394. 33 ± 201. 31 before surgery, and was 2283. 30±217. 82 at 3mo(P>0. 05). The percentage of corneal hexagonal endothelials was 52. 67％±6. 28％ preoperatively, and came to 51. 81％± 6. 41％ at 3mo ( P>0. 05 ). The central corneal thickness (mm) was 541.10±40.31 at the beginning, and was 543.10 ±41. 77 at 3mo (P>0. 05). Small amount of bleeding under choroid occurred in one eye, and intraocular lens dropped into vitreous body in another. Dislocation or shifting of intraocular lens, corneal decompensation or retinal detachment was not observed.? CONCLUSION: The clinical effect of secondary suspensory foldable intraocular lens implanted in aphakia eyes after vitrectomy was satisfactory. Minimal invasive surgery through small incision and accurate implantation are applied to increase safety while reducing complications, thus improve the effects of surgery.
