Abstract: Objective To explore the clinical characteristics and treatment method of cataract blindness screening crystal solubility in glaucoma. Methods The clinical data of 7 cases diagnosed as crystal solubility glaucoma were retrospectively analyzed. Admitted to hospital after diagnosis, they were given phacoemulsification to remove the lens. Results There were crystals dissolve glaucoma in 4 cases, uveitis secondary glaucoma in 2 cases, and age-related cataract overmature in 1 case which had specialized examination after hence dissolved lens membrane rupture cortex. 6 cases had their postoperative intraocular pressure decreased to normal in 1 day, 1 case had the postoperative intraocular pressure decreased to 30 to 42 mmHg in 3 days and had it gradually be back to normal after repeated anterior chamber fluid and drug treatment in 2 weeks. Followed up in 3 months, visions were all increased. Conclusion Crystal solubility in glaucoma patients is difficult to be diagnosed. Anterior chamber irrigation after cataract extraction is the effective way for crystals dissolve glaucoma. There are still more patients with cataract overmature period in the backward area.
