AIM: To observe the clinical results of innercapsular phacoemulsification with primary intraocular lens(IOL)implantation in the treatment of lens dislocation.

METHODS: A total of 23 cases(23 eyes)of lens dislocation(IIa and IIb)were underwent innercapsular phacoemulsification combined with primary IOL implantation. IOL implantation were underwent during operation, the complications of intraoperative and postoperative, postoperative vision, intraocular pressure(IOP), corneal endothelial cell, IOL location were analyzed.

RESULTS: The operations were successfully completed for all patients in accordance with the pre-surgery program; lens nucleus or its fragments did not crash into the vitreous cavity; 20 cases of corneal edema and 17 cases of IOP presented at the first day after surgery, the deviation or displacement of IOL and serious complications such as retinal detachment were not appeared. At the first week postoperation, the average IOP was 15.81±2.10mmHg, with statistically significant differences when compared with the preoperative(P<0.01), the visual acuity in all eases increased, with statistically significant differences when compared with the preoperative(P<0.01). Corneal endothelial cell density and percentage of hexagonal cells decreased, the variation coefficient increased in first week of postoperative, with no statistically significant differences when compared with the preoperative(P>0.05)

CONCLUSION: Innercapsular phacoemulsification combined with primary IOL implantation in the treatment of the whole lens dislocation(Ⅱa and Ⅱb)can restore function in patients with diplopia and control IOP effectively, reduce corneal endothelial cell damage, which is an effective method to treat the whole traumatic lens dislocation.
