Eye surgery , also known as ocular surgery, is an operation performed on the eye or its adnex, usually by an ophthalmologist. The eye is a very fragile organ, and requires extreme care before, during, and after surgical procedures to minimize or prevent further damage. An expert eye surgeon is responsible for choosing the right surgical procedure for the patient, and to take the necessary precautions. The name of eye surgery can be found in some ancient texts since 1800 BC, with cataract treatment beginning in the fifth century BC. Today continues to be a widely practiced type of surgery, having developed various techniques for treating eye problems.

Preventive and precautionary measures
Because the eye is strongly supplied by nerves, anesthesia is very important. Local anesthesia is most commonly used. Topical anesthesia using a lidocaine top gel is often used for rapid procedures. Because topical anesthesia requires cooperation from patients, general anesthesia is often used for children, traumatic eye injury, major orbitotomy and for worrying patients. An anesthesiologist, an anesthesiologist or an anesthesiologist with expertise in eye anesthesia, monitors the patient's cardiovascular status. Sterile awareness is taken to prepare the area for surgery and reduce the risk of infection. These precautions include the use of antiseptics, such as povidone-iodine, and sterile curtains, dresses and gloves.

Laser eye surgery
Although the terms laser eye surgery and refractive surgery are usually used as if they can be exchanged, this does not happen. Lasers can be used to treat non-biased conditions (eg to close retinal tears). Laser eye surgery or laser corneal surgery is a medical procedure that uses lasers to reshape the surface of the eye. This is done to improve myopia (nearsightedness), hypermetropia (long vision) and astigmatism (curvature of uneven eye surfaces). It is important to note that refractive surgery is not compatible with everyone, and rarely anyone may find that glasses are still needed after surgery.
The latest developments also include procedures that can change the eye color from brown to blue.
Cataract surgery
Cataracts are turbidity or opacification of the eye crystal lens due to aging, disease, or trauma that usually prevents light forming a clear image on the retina. If vision loss is significant, surgical removal of the lens may be necessary, with optical loss of power usually replaced by a plastic intraocular lens (IOL). Because of the high prevalence of cataracts, cataract extraction is the most common eye surgery. Rest after surgery is recommended.
Glaucoma surgery
Glaucoma is a group of diseases affecting the optic nerve that causes vision loss and is often characterized by an increase in intraocular pressure (IOP). There are many different types of glaucoma surgery, and variations or combinations of them, which facilitate the release of aqueous humor from the eye to lower intraocular pressure, and some that decrease IOP by reducing aqueous humor production.
Canaloplasty
Kanaloplasty is an advanced non-penetration procedure designed to improve drainage through the natural eye drainage system to provide sustained reduction in IOP. Kanaloplasty uses microcatheter technology in simple and minimally invasive procedures. To perform canaloplasty, the ophthalmologist makes a small incision to gain access to the channel in the eye. The microcatheter surrounds the duct around the iris, enlarging the main drainage channel and the smaller collector channel by injection of a material such as a sterile gel called viscoelastic. The catheter is then removed and the stitches are placed inside the duct and tightened. By opening the channel, the pressure inside the eye can be reduced.
Refractive surgery
Refractive surgery aims to correct refracting errors in the eyes, reduce or eliminate the need for corrective lenses
- Keratomilleusis is a method of reshaping the corneal surface to change its optical power. The corneal disk is shaved off, quickly frozen, ground lathe, then back to its original strength.

- Leeway/attenuation procedure
Oculoplastic surgery
Oculoplastic surgery, or oculoplastics, is an ophthalmological subspecialty associated with eye reconstruction and related structures. The oculoplastic surgeon performs procedures such as eyelid repair of the eyelid (blepharoplasty), improvement of tear duct obstruction, orbital fracture repair, removal of tumors in and around the eye, and facial rejuvenation procedures including laser skin coating, eyebrow elevator, and even a facelift. The general procedure is:

Orbital Surgery
- Ocular orbital/prosthetic reconstruction (False Eye)
- Orbital Decompression for Grave Disease. Grave disease is a condition (often associated with an overactive thyroid problem) in which the eye muscles swell. Because the eye sockets are bones, there is no place for swelling to be accommodated and as a result the eyes are pushed forward into prominent positions. In some patients this is felt. Orbitial decompression involves removing some bones from the eye socket to open one or more sinuses and making room for swollen tissue and allowing the eye to return to its normal position.

Other operations
Many of the procedures described are historical and not recommended because of the risk of complications.
