Retinal detachment, if not treated surgically, when the patient has cataracts, can be treated surgically after the cataracts are detected; if surgical treatment has been done, cataract surgery is usually considered more than three months after the retinal detachment surgery. Retinal detachment can lead to symptoms such as loss of vision and visual field defects. It should be treated as early as possible, and the sooner the retina is reset by surgical treatment, the better the recovery usually is. If the patient has cataracts, surgery can be performed as soon as it is detected in order to identify the retinal detachment as soon as possible and decide whether it is possible to surgically reset the retina, to unblock the cataracts from blocking the light, and to facilitate the observation of the patient’s fundus lesions. If a patient has already had surgery to reset a detached retina and then develops a cataract, it is usually safer to have cataract surgery about three months after the first surgery. Specifically, you can go to the local hospital ophthalmology consultation, the doctor according to the specific circumstances to determine the treatment plan and time.
