Secondary cataract refers to opacity and thickening of the posterior lens capsule, leading to vision impairment.
Secondary cataract, because of its name and similar symptoms, is often confused with another disorder, namely, the cataract itself. There is a widespread belief that the secondary cataract diagnosis means that the cataract has recurred, for a second time. This misconception is related to the fact that a secondary cataract can be formed only after the primary cataract.
The nature of these conditions and treatment options are completely different. In cataracts, vision is impaired due to opacity of the crystalline lens, and in secondary cataracts, due to thickening of the posterior capsule of the crystalline lens (a thin elastic bag), which actually houses the crystalline lens, either naturally or artificially. The thickening prevents the light beams from passing through the refractive structures of the eye to the retina, and the visual acuity decreases.
What is the origin of a secondary cataract?
Secondary cataract arises from cellular reactions that occur in the capsular bag. Epithelial cells grow on the posterior surface of the lens capsule, forming a film. It blocks the light from reaching the retina. This reaction can be triggered by various factors, including body peculiarities, systemic diseases (diabetes mellitus, rheumatism, and others).
Secondary cataract symptoms:
Secondary cataract can develop within several months or years after surgery. The closer the epithelial film is formed to the central part of the lens, the more obvious the signs of the disease will be.
Secondary cataract is characterized by decreased visual acuity and a kind of flickering before the eyes. Color sensitivity may deteriorate. The person suffering from this pathology often sees the world with a yellowish tint. Blurred vision, glare from the sun and light sources, double vision, difficulties in focusing and defining the shape and size of surrounding objects. If you experience these alarming symptoms, you should never hesitate to visit a specialist!
Secondary cataract treatment
Secondary cataract treatment allows getting rid of the disease and regaining the original visual characteristics. Eximer Ophthalmology Clinic applies the most effective, non-invasive method of treating secondary cataracts with the YAG laser.
During secondary cataract surgery (laser capsulotomy or secondary cataract discision), parts of the overgrown epithelium are removed from the visual field, and visual acuity is fully restored. The YAG laser is safe for eye structures, it focuses and affects only specified areas and does not damage the crystalline lens.
Procedure for secondary cataract laser treatment
At Eximer Ophthalmology Clinic, secondary cataract surgery is performed:
- In a single day mode, i.e., on an outpatient basis;
- With local droplet anesthesia;
- Absolutely painless.
The patient settles comfortably in the chair. The procedure takes just several minutes, the visual characteristics are restored immediately after the treatment, so the person does not lose working capacity. Subsequently, there are no restrictions on physical and visual activity.
