Secondary cataract is clouding and roughening of the posterior lens capsule which affects vision acuity. Due to its medical name and similar symptoms, secondary cataract is often mistaken for cataract proper. There is a widespread opinion that “secondary cataract” means recurring cataract. This is a misconception due to the fact that secondary cataract can only develop after the primary cataract.
The origins of these conditions and methods of treatment are completely different. The main cause of vision reduction in case of cataract is clouding of the lens, while in case of secondary cataract it is roughening of the posterior lens capsule, a thin elastic membrane which houses the lens, be it natural or implant. Roughening inhibits transmission of light to the retina, therefore, vision acuity reduces.
What are underlying causes of secondary cataract?
Secondary cataract is the result of cell responses inside the lens capsule – epithelial cells start growing on the posterior surface of the lens capsule to form a membrane. This membrane is the obstruction on the way of light transmission. Such response can be triggered by a variety of factors including individual specifics, systemic diseases (diabetes, rheumatism, etc).
Symptoms of secondary cataract:
- gradual vision reduction;
- halos around sunlight and artificial light;
- blurry vision.

Treatment of secondary cataract
Suitable treatment regimens help eliminate secondary cataract and restore vision to its state before the disease. Excimer uses the most effective non-surgical method of secondary cataract treatment – YAG laser-assisted therapy. During the laser-assisted procedure (laser capsulotomy or laser discission of secondary cataract), proliferating epithelium particles are removed from the field of vision, thus visual acuity is fully restored. YAG laser is totally safe for optical organs, has a precise focus and affects only those areas that are within its focus, without damaging the lens.
What does the laser-assisted procedure look like?
At Excimer, we use a “one-day” approach for laser-assisted treatment of secondary cataract; that is, our patients are not hospitalized. To make the procedure absolutely painless, we use eye drop anesthesia. During the procedure, which takes only several minutes, the patient sits comfortably in the chair. The vision is restored right after the procedure, so the patient can resume work right after treatment. There are no limitations as to exercise or eye strain later.
