The medical specialty that deals with the diagnosis and treatment of eye diseases is known as ophthalmology. The surgical sub-specialty within this field is known as ophthalmic surgery. It involves the surgical procedures performed on the eyes or its surrounding structures to correct various eye conditions and improve visual function. Some of the common types of ophthalmic surgeries are cataract surgery, refractive surgery and retinal surgery. Cataract surgery involves the removal of a cloudy lens, known as the cataract, from the eye and replacing it with an artificial intraocular lens in order to restore clear vision. Refractive surgeries, such as LASIK, photorefractive keratectomy and small incision lenticule extraction, aim to correct vision problems such as nearsightedness, farsightedness, astigmatism and presbyopia. This book is compiled in such a manner, that it will provide in-depth knowledge about the ophthalmic surgery. It includes contributions of experts and scientists which will provide innovative insights into this field of medicine.
