Cataract Surgery in Very Old Patients

Background In recent years, there has been an increase in the number of very old patients requiring a cataract operation. However, there is little information on the intraoperative complications and safety in these patients. For various reasons, operations on patients from age 85 may be demanding: dense nuclear cataract, narrow pupils, low count of endothelial cells, loose zonula, and other ocular or systemic diseases. The aim of this retrospective study was to compare very old to younger cataract patients with respect to intraoperative complications and the maturity of the cataract. Patients and Methods This was a retrospective study on 4065 cataract patients treated in our department with IOL implantation with the corneal small incision technique between January 2015 and January 2018. The patients were split by age (from 85 and under 85). Results Of the 4065 cataract operations, 10.6% (431/4065) were performed on patients aged at least 85, 1.7% (69/4065) on patients aged at least 90 and 0.1% (4/4065) on patients of at least 95 years. There were statistically significant differences between the younger and older patients with respect to pupil dilatation (4.6 vs. 6.0%), use of the capsule tension ring (0.4 vs. 0%) and in capsule staining (5.5 vs. 7.0%). There were no intraoperative complications (e.g. anterior capsule laceration) in patients aged at least 85 and in 0.71% of patients aged under 85; loss of vitreous fluid was recorded in none of the patients in the older group and in 0.41% of patients in the younger group. Conclusion Our study confirms that advanced age alone is not a contraindication for a cataract operation and is not associated with a greater rate of intraoperative complications. Cataract operations on very old patients are generally successful, but should be undertaken early - particularly on multimorbid patients or those with dementia - in order to support the psychological status. The age of the patient is irrelevant.
