If you were born blind, is there a chance you can get sight with surgeries/medical intervention?

While there are some medical procedures and technologies that can help improve or restore vision in individuals who are blind due to certain eye conditions or visual impairments, the outcomes can vary, and not all cases result in complete or functional sight.

1. Corneal Transplantation: Corneal transplantation, also known as a corneal graft or keratoplasty, is a surgical procedure that can restore vision in some cases. It is primarily used to treat corneal conditions that affect the clarity and transparency of the cornea, such as corneal scarring. The success of corneal transplantation depends on the specific condition and the individual's overall eye health.

2. Cataract Surgery: Cataracts, a clouding of the eye's natural lens, can cause significant vision loss. Cataract surgery involves removing the cloudy lens and replacing it with an artificial intraocular lens (IOL). This procedure often results in significant vision improvement.

3. Retinal Prostheses (Bionic Eyes): Some research and development efforts have focused on retinal prostheses, also known as "bionic eyes." These devices are designed to restore partial vision to individuals with certain retinal conditions, such as retinitis pigmentosa. One example is the Argus II Retinal Prosthesis System.

4. Gene Therapy: In some cases of congenital blindness caused by specific genetic mutations, experimental gene therapy treatments have shown promise in restoring vision or preventing further vision loss.

It's important to note that the success of these procedures and technologies varies, and not all individuals with blindness or visual impairment can benefit from them. Additionally, there are different types and causes of blindness, and not all cases can be addressed through surgical or medical interventions. 

Furthermore, for individuals who have been blind from birth, the process of gaining functional vision after surgery or implantation can be complex. The brain's visual processing pathways may not have developed fully, which can affect the ability to interpret visual information even if some level of sight is restored. Visual rehabilitation and training may be necessary to help individuals adapt to their newfound vision.
