| Popis: | Purpose: is to evaluate the effectiveness of YAG laser posterior lens capsule dissection in patients with secondary cataract with concurrent intraocular pathology. Patients and methods: retro- and prospective analysis of the results of the YAG — laser treatment of secondary cataract in the 196 eyes, including the intraocular concomitant pathology (myopia, glaucoma, age-related macular degeneration, diabetic retinopathy, retinitis pigmentosa operated retinal detachment, chronic uveitis in remission, peripheral chorioretinal degeneration). Effectiveness of treatment was evaluated by checking visual acuity and dynamics of complaints as aberration, glare, distortion in the central field of view without proper disease of the macula. Complex preoperative studies included: refractometry, visometry with correction, perimetry, tonometry, biomicroscopy, ophthalmoscopy, ultrasound examination of the eyeball (if necessary). The examination results should demonstrate convincing evidence that posterior capsular opacification is the main reason for the decrease of visual acuity. Results:, Visual acuity, at average increased from 0.4‑0.6 to 0.8‑1.0 in 50 cases after dissection, Visual acuity improved to 2‑3 lines in 66‑4–5, 24‑6‑7 lines in 74 cases. Visual acuity remains the same, but contrast sensitivity was increased in 6 cases. The IOL location after disruption was evaluated by β-scanning and biomicroscopy. In case of the initial correct IOL position in all 195 (100 %) cases, there were no dislocation in the postoperative period. Complications that can be identified were single microcraters on the IOL surface in cases of its full contact with the posterior capsule. These injuries did not affect the visual functions.Conclusion: YAG -Laser dissection of secondary cataract is effective, less traumatic, and the optimal treatment of secondary cataract, including patients with concomitant intraocular pathology, and helps to avoid over diagnosis of visual field check among patients with open-angle glaucoma. |
