ABSTRACT

A double masked placebo controlled multicentric randomised clinical trial was conducted in 157 patients suffering from different eye ailments namely, cataract, dry eye syndrome, ocular asthenia, refractive errors and allergic conjunctivitis with a herbal eye drop preparation and placebo. In both dry eye syndrome and ocular asthenia the herbal eye drop preparation was found better than placebo. In a few cases of cataract, the vision seems to be improved. In early myopia it seems to correct the refractive errors while in high myopic conditions it controlled the progressive deteriorations. Subjective improvements were also noted with hypermetropia, presbyopia and astigmatism. Its healing capacity in allergic conjunctivitis was certainly better than placebo. It had no short term or long term side-effects. It is considered to be a useful drug in all conditions studied.
