Aim Of The Study: Evaluation of effectiveness of Catalin eye drops in inhibition of cataract or eventual influence on regression of actually present opacities.

Patients And Method: 72 patients in age over 40 years with initial cortical cataract and visual acuity better than 0.5 were evaluated. 35 patients were treated with anticataracous drug Catalin, and 37 received placebo. All patients were evaluated with a slit-lamp and modern equipment EAS-1000 (Nidek) before starting research and after 3, 6, 12, 18 and 24 months of treatment.

Results: Catalin-eye drops in patients with cortical cataract showed its effectiveness in inhibition of lens opacification and its progression especially in group of patients in age up to 59 years. The increase of lens opacification in this group was only 1.425% (Catalin), and in older group (placebo) even 9.228%. Appropriate, raising effect of the drug can be observed after 18 months of treatment. Catalin-eye drops did not cause any complications during the study.

Conclusions: 1. Catalin-eye drops used in patients with senile and presenile cortical cataract is effective drug in inhibiting lens opacification. 2. The function of the drug is more obvious in group of younger patients (up to 59 years of age) in comparison with older ones. 3. Appropriate, raising effect of the drug can be observed after 18 months of treatment. 4. Catalin-eye drops is well tolerated by the patients even after prolonged application.

The present investigation studied the efficacy of Catalin eye drops (Senju Pharmaceutical Co, Osaka, Japan) in patients with early senile cataract. An objective procedure for the densitometric analysis of lens transparency images with a Pentacam apparatus (Oculus GmbH, Germany) was used to assess the results of the investigation. Unlike the control group, the patients using Catalin had a lower optical density in the anterior and posterior cortical lens layers and beneath the posterior capsule in the first months of therapy.

Clinicopathological studies were performed on 156 lenses of human senile cataract obtained by cataract operations between 1970 and 1988. It became clear that the aging influences the functional destruction of the equatorial region, the pathological changes of the bow area, and changes of the extralens environment. After operation for the atrophic type of the posterior subcapsular cataract, aftercataract easily develops on the intraocular lens and this requires treatment.
