AIM:To investigate the clinical effect of hypermature cataract extraction combined with intraocular lens implantation by the tongue capsulotomy method.

METHODS:A total of 380 eyes with hypermature cataract were applied tongue capsulotomy method in cataract extraction combined with intraocular lens implantation. All of eyes were observed and followed up the effect after operation.

RESULTS:The visual acuity of all cases was improved after the operation. One day after operation, 85 eyes(22.4%)were below 0.1, 162 eyes(42.6%)were between 0.1 to 0.3, 87 eyes(22.9%)were between 0.4 to 0.6, 46 eyes(12.1%)were above 0.6. One month after operation, 33 eyes(8.7%)were below 0.1, 152 eyes(40.0%)were between 0.1 to 0.3, 117 eyes(30.8%)were between 0.4 to 0.6, 78 eyes(20.5%)were above 0.6. Intraoperative or postoperative complications:intraoperative suspensory ligament broken occurred in 16 eyes(4.2%), posterior capsular rupture occurred in 25 eyes(6.6%), 53 eyes(13.9%)were found corneal edema, 12 eyes(3.2%)were found artificial crystal offset.

CONCLUSION:The tongue capsulotomy method is easy to grasp, the security of this method is better than others. It is more suitable for the use of hypermature cataract extraction combined with intraocular lens implantation during aid Africa.
