Classification of Eye Surgery
Eye surgery is also termed as orogolomistician surgery and is performed by special group of surgeons called as ophthalmologists who are basically both medical consultants as well as surgeons. Types of eye surgery can be broadly classified into three types that are described below.
1) Laser eye surgery
Laser based type of eye surgery is used for refractive imperfections in the eyes such as near-sightedness and far-sightedness and also some times used for non-refractive imperfections. Laser based eye surgeries can be divided into the following:
LASIK: This surgery is used to correct the eye power for example short sight and far sight, Here the laser is used to reshape or remove a tissue under the cornea. This is the most common form of laser surgery is extremely quick.
LASEK: This type of surgery is performed on those patients whose cornea is too thin. Hence instead of inner layer, outer layer of cornea is used to cut the flap. LASEK eye surgery requires much more care and needs more time to heal. Apart from this there is no other difference between LASEK and LASIK.
PRK or Photo refractive Keratectomy is again used to remove the corneal surface imperfections that decrease the vision power of a human eye. There is not much difference between the PRK and LASEK as both the surgeries are performed on the patients who have a very thin and delicate cornea.
2) Non Laser Eye Surgery
As the name suggest, this type of eye surgery do not involve the use of laser for any type of eye corrections. Here the surgeon uses traditional tools such as blade and scalpel. Blades or heat waves are used to change the shape of the corneal surface. Most of the times, a lens is planted permanently in the eyes. In the recent years, the number of people opting for non laser eye surgery has gone down considerably due to advancement in laser treatments.
Laser Eye Surgery can further be divided into following types.
Glaucoma Surgery: This type of surgery is used to treat the loss of vision due to the high pressure inside the eye. Glaucoma surgery generally involves opening up of the eye canal to reduce the pressure.
Oculoplastic Surgery: This eye surgery involves the fixing of eye lids that droop too much or for fixing the tear ducts and also reconstruction of eye structure and other parts around it.
Cataract Surgery: Cataract is condition that normally occurs during old age where vision gets blurred due the growth of additional layer on the human eye lens. A cataract surgery is used to treat this type of condition and is one of the most common forms of eye surgeries.
3) Cosmetic Eye Surgery
This is the third classification of eye surgery and is used for changing the appearance of the eyes including the eye lids. The overall appearance and look of an eye is improved by this surgery.
