Glaucoma, Cataract, and Diabetic Retinopathy are eye diseases with similar indicators vis-a-vis high pressure on the eye, optic nerve damage, and seldom vision loss. Loss of sight may occur if the patient is not treated, it affects the bordering visualization. Diagnosis of ocular diseases at the initial state necessitates consistent check-ups which is time consuming as well as too expensive. This research work suggests a Hierarchical Fuzzy decision system which is built for analyzing and treating Diabetic Retinopathy, Glaucoma & Cataracts at very early state along with a very price-effective procedure room illumination Keratoscope which can be installed for handling the case of uneven corneal curvature, surgery for cataract & even Full-thickness corneal graft. The hierarchical Fuzzy-rule mechanism proposed in this research assists the medicinal experts in the diagnosis of the result with precision given the patient’s symptoms. All the tests were done on the proposed system and even the testing of feasibility of the Keratoscope were undertaken under the supervision of an eye care specialist and were scribed to be accurate and beneficial, evaluating accuracy to 93%, sensitivity to 94% and specificity to 92 %. This technique is effective and has a small cost of computation
