This study deals with the cataractous lenses removed from the patients residing in a rural area like marathwada region and was done at S.R.T.R. Medical College Ambajogai. This topic was chosen as this type of study has never been done before in this region. From anatomical point of view the morphologic features of the lens nuclei removed by extracapsular cataract extraction method are studied and compared with age and sex of patient. Materials and methods: The lens nuclei removed by extracapsular extraction method were collected in plain bulbs and preserved in 10% formalin for morphological observations. Detailed case history of the patient is recorded. Colour of lens nuclei was recorded and changes in diameter, thickness and wet weight of lens nuclei according to colour were studied. Diameter and thickness was measured with vernier caliper while weight is measured with two pan scientific balance. Pirie’s classification was used to divide the lens in four groups. Results: According to our study mean diameter of lens nuclei goes on increasing from Group I to Group IV in both men and women and similar findings are observed for mean thickness and weight of lens nuclei in both male and female. Discussion: Our study found statistically significant increase in thickness, diameter and weight of lens as the colour of lens nuclei deepens. Our findings are compared with other workers. These morphological findings may be useful for the ophthalmologists to correlate with their clinical observations. Conclusion: Our study found that morphological parameters of lens change as its colour deepens.
