There are many operative diseases in the field of ophthalmology like contract surgery, cornea transplant, strabismus surgery and many others. The Sydney Eye Hospital Foundation specialises in eye surgeries with state-of-the-art technology and eye care for adults and children. There are a wide range of conditions that call for eye surgery including cosmetic vision-saving procedures. Whether it is corrective treatment or a more complicated procedure like orbital implants, the advancements in eye technology have given opthalmologic surgeons the ability to tackle almost any condition.

Corrective Surgery
Corrective eye surgery is one of the most popular types of opthalmologic surgery available today. ASIK (Laser-Assisted in Situ Keratomileusis) and PRK (photorefractive keratectomy) are the two most common methods. These surgeries can correct conditions like myopia, hyperopia and astigmatism, and can result eliminate the dependency on corrective lenses.

Cataract
Cataracts, which typically occur in adults over 60, are treated using three different methods. Phacoemulsification is the most common and applies ultrasonic vibrations to dissolve the cloudy lens using an inserted probe. If the lens is too dense a surgeon will opt for extra-capsular surgery that requires the manual expression of the lens through a large incision made in the cornea or sclera. Intra-capsular surgery is very rare and requires a large incision in order to remove the entire lens and surrounding capsule.

Glaucoma Surgery
Surgery for glaucoma does not reverse vision loss, but helps to reduce its progression. The two types of surgery include laser and conventional.
Lid Repair Surgery
Lid repair surgery is performed for cosmetic and functional reasons. It is used to treat ptosis (droopy eyelids), which can obstruct vision and age the patient visually.

Orbital Surgery
Orbital eye surgery is used for individuals with congenital defects resulting in absent eyes, large eye tumours, or when the eye cannot be preserved due to trauma. Orbital implants are used to preserve the natural structure of the eye orbit and provide support for the placement of an artificial eye.

Opthalmologic surgery is a prevalent part of modern society today and upgrades in lasers and biocompatible materials have created a new level of safety and success for patients who required these procedures.
