Introduction: Senile white cataracts are special cases in cataract surgery since they are associated with unique set of complications not seen in immature cataracts. The major drawback while operating on a white cataract is lack of nuclear details like its density or size. This study was conducted to establish nuclear size in mature and hypermature senile cataracts. Materials and Methods: The study involved intact nucleus obtained during manual small incision cataract surgery. The cases were grouped into mature or hypermature category. The nucleus was measured directly using electronic scale on a smartphone calibrated to measure up to 10 micrometers. The thickness and diameter of nucleus were recorded. These values and ocular parameters obtained by immersion A-scan preoperatively were analyzed. Results: The mean nuclear thickness in mature cataracts was 3.66 mm (3.17 to 4.38) and in hypermature cataracts was 3.36 mm (2.66 to 3.95). There was significant difference in nuclear thickness and lens thickness between the two groups. The nuclear diameter did not vary significantly between the two groups. Conclusion: The nucleus in mature cataract is significantly thicker than that of hypermature cataract and occupies most of the lens volume indicating a dense nucleus. During phacoemulsification of mature cataract, it is advisable to increase the machine parameters to tackle this dense nucleus. While in case of hypermature cataract the machine parameters should be lowered as, the nucleus is thinner and less dense.

Abstract

Introduction: Corneal transplantation is a sight restoring procedure that enhances the recipient’s quality of life. The number of corneal transplants which were done is very low when compared to requirements in India. This is largely due to the inadequate number of corneas collected. Nursing staff can influence eye donation rates. Materials and Methods: A cross-sectional study was conducted among 59 nurses of Basaveshwara Medical College and Hospital, Chitradurga in July 2018. Primary information was collected by interview technique by using a pre-tested semi-structured questionnaire. The data was analysed and presented in simple proportions. Results: Among total 59 nurses, 36 (61%) were aged 21 to 30 years and 18 (30.5%) were aged between 31 to 40 years. Study participants had good knowledge regarding eye donation. 89.8% nurses were willing to donate their eyes. On the whole nursing staff had good attitude towards eye donation. Conclusions: The nursing staff have good knowledge and attitude towards eye donation. Still further research on attitude of nurses and other professionals on good amount of sample and also better health education programs regarding the organ/eye donation process. Keywords: Awareness, Blindness, Corneal donation, Nursing staff.
