This study tests if a direct injection of the drug rituximab into eye tumors works as well as standard radiation therapy for a rare eye lymphoma (MALT lymphoma). About 108 adults aged 18-75 will be randomly assigned to one of the two treatments. The goal is to see which approach …

This study looks at whether placing a small support ring (capsular tension ring) during cataract surgery helps keep the artificial lens more stable in people who also have retinitis pigmentosa, an eye disease that causes vision loss. Each of the 88 participants will get the ring …
