Ophthalmology
Ophthalmology is the branch of Medicine / Surgery which deals with the diseases of the eye and their treatment.
The word ophthalmology has an "h" after the "p". The first syllable is pronounced "aahf," like the "oph" in "sophomore." It comes from the Greek root "ophthalmos-" meaning "eye;" ophthalmology literally means "the science of eyes."
Ophthalmology includes sub-specialities which deal either with certain diseases or diseases of certain part of the eye. Some of them are:
- Cornea and Ocular surface
- Glaucoma
- Lens
- Blindness
- Surgery
- Retina and Vitreous
- Uvea
- Strabismus (Squint),
- Paediatric Ophthalmology
- Ophthalmoplasty
- Eye Trauma
Cataract surgery is a major sight-giving operation that eye surgeons perform by removal of the opaque human lens and replacement with an artificial Intraocular lens implant.
Phacoemulsification is keyhole surgery with emulsification and aspiration of cataract through a 2.8-3 mm incision and placement of a foldable intraocular lens through the same unenlarged incision. This gives faster rehabilitation and excellent results in trained hands.
LASIK (Laser assisted-in-situ keratomilieusis) is a type of refractive surgery whereby an excimer laser (193 nm) is used to remodel the corneal stroma after lifting a partial thickness corneal flap made by a microkeratome. Excimer laser ablates tissue without causing damage to adjacent stroma in a finely controlled manner. Major research is underway to improve the results and predictability of refractive surgery.
Regular examination of the eyes is highly important in ensuring the preservation of sight.
