Purpose
In patients with cyristalline lens subluxation cataract surgery presents several challenges compared to standard ones. A detailed pre-operative evaluation and surgical planning are mandatory in these patients, and various surgical techniques such as Cionni capsular tension ring, Ahmed segment, Canabrava method have been described as treatment options. The aim of this study was to present the results of sclerocorneal monofixation (Telegin method) in patients with lens subluxation.
Setting
The study was conducted at Ege University Faculty of Medicine.
Methods
The study included 22 eyes of 17 patients who underwent surgery for lens subluxation and/or zonular weakness/dialysis. Zonular weakness due to trauma (4 eyes of 4 patients) and zonular weakness or laxity (18 eyes of 13 patients) were the primary reasons of lens subluxation. Capsulorhexis was performed in all patients and iris retractors were used to stabilise the capsular bag. After phacoemulsification, a 30-gauge needle and an 8/0 prolene suture were placed, with one end of the suture turned into a knob under the intraocular lens (IOL) and the other end on the cornea. Post-operative lens stabilisation, suture exposure and IOL tilt were evaluated.
Results
The mean age of the patients was 62.43±4.67 (29-74) years. In 5 patients the surgery was bilateral. Mean follow-up was 9.3±3.1 (3.4-19) months. Mean visual acuity was 0.27±0.19 (0.05-0.7) pre-operatively and 0.83±0.32 (0.3-1) post-operatively (p<0.001). Mean intraocular pressure was normal and similar before and after surgery. None of the patients had suture exposure in a minimum follow-up of 3.5 months. No subluxation, dislocation or tilt of the IOL was observed during follow-up.
Conclusions
Cionni ring and Ahmed segments have been used for many years in patients with crystalline lens subluxation due to significant zonular dialysis, with very successful results. Telegin method has achieved long-term lens stability at a much lower cost.
