Abstract: We report a case of a patient with a highly hyperopic eye who underwent cataract surgery combined with vitreous surgery to create a posterior vitreous detachment (PVD) to prevent choroidal neovascularization (CNV). A 78-year-old man noticed a decrease in his vision due to a cataract in his right eye. The patient had a severe visual loss in his left eye because of a CNV 2 years after a cataract surgery. His visual acuities were 20/30 OD and 20/600 OS, and funduscopic examination showed an orange-colored lesion OD and degenerative subretinal fibrosis OS. The posterior vitreous was attached to the retina in both eyes. The axial length was 18.9 mm OD and 19.0 mm OS. Cataract surgery combined with vitreous surgery to create PVD was performed on the right eye, and the vision improved to 20/20 with no signs of developing CNV after 5 years. We conclude that cataract surgery combined with vitreous surgery to create a PVD may prevent the development of CNV in highly hyperopic eyes.
