Development and research of clinical efficiency of technique of long-term correction of aphakia when performing extraction of the age-related cataract through small cuts in eyes with the first degree of a lens subluxation.
The Khabarovsk branch of the State Institution Eye Microsurgery Complex named after S.N. Fyodorov, Khabarovsk, Russia
The short of the technique consists in carrying out a phacoemulsification through a corneal tunnel of 2.2 mm. Necessarily the iris retractors stabilize capsular bag. After excision of lens masses it is removed noninvasively and through a cartridge the IOL RSP-3 is implanted which is grafted to an iris by nylon 10-00. Two groups of patients with existence of 1 degree of the lens subluxation, comparable on age (on the average 73 years), sex, degree of cataract maturity were created. To all patients the phacoemulsification through a small corneal tunnel cut of 2.2 mm on the device Stellaris (Bausch&Lomb, the USA) was carried out. 30 eyes of 29 patients (the main group) were operated by this own technique. The group of comparison was made by 30 patients (30 eyes) to whom implantation of intracapsular ring with the subsequent implantation of posterior chamber IOL (Aqua sense, Acrysof natural, Acreos MI-60, Rayner) into a capsular bag was carried out during a phacoemulsification. Criteria of comparison: correctness and stability of IOL situation, frequency of intra- and postoperational complications. Term of observation made 1.5-2 years.
In the general set of eyes all operations were performed per plan, without complications. For 1-2 days the correct IOL situation took place in all eyes of the main group (100%). In 2 eyes of the group of comparison there was an appreciable shift of the complex "capsular bag-intracapsular ring-IOL" in the vitreous cavity, demanded its excision through broad scleral access 5.0-5.5 mm, a forward vitrectomy and IOL RSP-3 implantation. 1.5-2 years later correctness and stability of IOL situation was defined in all eyes of the main group and in 24 eyes of group of comparison (80%). Vizometry indicators and the VGD level were correlative in both groups. Vizometry indicators made from 0,2 to 1,0 (on the average 0,69), the VGD level on the average 19,8 mm hg.
The developed technique allows to achieve higher stability of IOL situation, with a minimum intra- and postoperational complications, and lack of clinically significant induced corneal astigmatism.
