Implantation of intraocular lenses in patients with diabetes

The authors analysed and compared three groups of patients who had undergone surgery. In the first group of 72 patients with diabetes and cataract, intraocular lens implantation was carried out. In the second group of 96 patients with diabetes and cataract, cataract surgery was not followed by intraocular lens implantation. The third group of 100 nondiabetic patients, selected by random choice, had intraocular lens implanted after the cataract surgery. Retinal status, postoperative complications and visual acuity were the parameters analysed in correlation with the intraocular lens implantation. In the authors' opinion, the prognosis following cataract surgery and intraocular lens implantation in diabetic patients is good, if diabetic complications do not occur, particularly retinopathy and vitreal hemorrhage which impair the vision considerably. Intraocular lens can be implanted even in cases of maculopathy and preproliferative diabetic retinopathy, provided a thorough diagnostic evaluation has been performed (echography, fluorescein angiography). Laser photocoagulation procedure should also be carried out before surgery and repeated as long as the transparence of the lens enables it. The treatment should be resumed two weeks after the cataract surgery and intraocular lens implantation at the latest. Intraocular lens implantation is contraindicated in proliferative diabetic retinopathy, and especially iridal rubeosis, as the risk of neovascular glaucoma development is considerable.     

The Experimental Study on Implantation of Intraocular Lens in Different Animals

To prevent the complications in cataract surgeries, the eyes of rabbits and monkeys were implanted with intraocular lens for 360 days. Methods: The eyes of the rabbits were performed with phacoemulsification and soft intraocular lens implantation. The eyes of the monkeys were performed with extracapsular cataract extraction and hard intraocular lens implantation. Results: The postoperative reactions included corneal edema, anterior chamber exudation, posterior capsule opacification and so on. The complications in the eyes of the rabbits were more than that in the eyes of the monkeys. Conclusion: The different postoperative reactions happened in different animals. In clinical the choice of the operative method and intraocular lens depended on the case in order to acquire the best sight.     

The evolution of cataract surgery,extra- and intraocular correction of aphakia

The evolution of cataract surgery during the recent 2 centuries, and especially in the last 50 years, witnessed essential changes--from reclination of the lens and a traditional extracapsular cataract extraction to cataract microsurgery including phacoemulsification. A lack of the lens in the eye, i.e. aphakia, is considered to be a serious complication. The optic extraocular correction of aphakia is implemented mainly by the use of spectacles and contact lenses, which are not deprived of essential shortcomings. H. Ridley was the first to implant, in 1949, a polymethylmethacrylate (PMMA) intraocular lens (IOL). After that, anterior-chamber and iris-clips lenses as well as extrapupillary lenses with fixation to Sulcus cyliaris, which had by some complications, were offered. Only in 1973, we offered, for the first time in the world practice, an intracapsular implantation and intercapsular fixation of IOLs of various models. The designed intraocular correction of aphakia was checked by time and it is used now in cataract microsurgery, including small-incisions as well as ultrasound and laser phacoemulsification. The use of the lens bag as a natural bed for the fixation and isolation of IOL from intraocular structures is a priority direction in the Russian research ophthalmology.     

Novel approach in the treatment of intravitreal foreign body and traumatic cataract: three case reports

We present a novel surgical technique of simultaneous traumatic cataract extraction, internal magnet removal of the intraocular foreign body, and implantation of a posterior chamber intraocular lens in the eyes of three patients with traumatic cataract and ferrous intraocular foreign body retained in the anterior part of the vitreous body. Primary corneal wound repair, cataract extraction, anterior vitrectomy, removal of the intraocular foreign body through the corneoscleral limbal incision by using intraocular magnet, and intraocular lens implantation were performed. All intraocular foreign bodies and corneal entry sites were not larger than 3 mm. After a median follow-up of 13.6 months (range, 9-21 months), visual acuity ranged from 0.6 to 1.0. There were no early or late postoperative complications. According to our experience, an anterior approach in the surgical technique of simultaneous cataract extraction, intraocular foreign body extraction and implantation of a intraocular lens in the capsular bag is possible in selected patients with intraocular foreign bodies positioned in the anterior vitreous, behind the lens, with no associated retinal pathology.
