Types of Eye Surgery

Refractive surgery

The goal of refractive surgery is to improve a patient’s vision. An individual who is either nearsighted or farsighted has a refractive error in the interior of their eye. Light entering the eye does not properly focus on the retina, instead focusing in front of the retina in nearsighted individuals or behind the retina in farsighted individuals. The result is that viewed images appear blurry and out of focus. Refractive surgery corrects this error, allowing light to focus directly on the retina, thereby improving vision and eliminating the need for corrective lenses.
There are numerous methods of refractive surgery, the most popular of which are LASIK (laser assisted in-situ keratomileusis), LASEK (laser assisted sub-epithelial keratomileusis) as known as Epi-LASIK, PRK (Photorefractive keratectomy), CK (conductive keratoplasty), and ICRs or Intacs (Intracorneal rings).

Corneal surgery

Corneal surgery is any surgery that involves manipulation of the cornea of the eye. This encompasses nearly all types of refractive surgeries since the cornea is modified in order to improve the individual’s vision. It also includes corneal transplant surgery, a procedure by which a damaged or diseased cornea is removed and replaced with a clear cornea from an organ donor. Other types of corneal surgery are PK (penetrating keratoplasty), PTK (phototherapeutic keratectomy), and Pterygium excession.

Glaucoma surgery

Glaucoma is a disease that attacks the optic nerve, resulting in loss of vision and a rise in intraocular pressure. Glaucoma surgeries assist in combating the disease by lowering intraocular pressure. This may be accomplished by decreasing the amount of aqueous produced in the eye or by encouraging the release of excess aqueous humor from the eye.

Cataract surgery

Cataract extraction is the most common eye surgery performed. Age, illness, or trauma to the eye can sometimes cause the crystalline lens of the eye to become cloudy and opaque. This cloudiness, called a cataract, interferes with the eye’s ability to focus a clear image on the retina, resulting in loss of vision. The presence of significant cataracts requires the removal and replacement of the lens through cataract surgery. Although there are a number of different types of cataract extraction, the two most popular procedures are called ICCE (intracapsular cataract extraction) and ECCE (extracapsular cataract extraction).

Oculoplastic surgery

Oculoplastic surgery is a type of eye surgery that concerns the reconstruction of the eye and its surrounding structures. Eyelid surgery, or blepharoplasty, removes excessive fat, muscle and skin from the eyelid to correct sagging or puffy eyes. Browplasty, often referred to as a brow lift, is the reconstruction of the forehead and brow bone. Oculoplastic surgery can also involve the removal of the eye itself. Enucleation involves the removal of the eye itself, leaving the muscles surrounding the eye and all orbital contents in place. Evisceration occurs when the eye and all of its contents are removed, leaving just the shell of the sclera in place. Finally, exenteration involves the removal of the entire orbital content. This includes the removal of the eye itself, any extraocular muscles, surrounding fat, and all connective tissues.

 

Headaches and Sunglasses

What most people don’t already realize is that many migraines and headaches can be prevented through the regular use of a good set of sunglasses! Regardless of whether it’s the summer solstice or the frigid depths of winter, a high quality pair of sunglasses is a very useful preventive health item as well as a fashion accessory. Since bright light can trigger migraines, headaches, and contribute to tension and other disorders, a good pair of sunglasses can significantly improve your quality of life, as well as preventing serious eye degeneration that can eventually lead to blindness.

An effective pair of sunglasses should block both UVA and UVB rays, but new research suggests that High Energy Visible (HEV) light may also contribute to eye disorders, particularly in children. There is still insufficient data on this subject, but some manufacturers now design to block UV rays as well as HEV light, reducing your changes or visual damage from light sources.

It’s very important to note that dark glasses are not the same as UV-exclusive glasses. Check to make sure that your shades are made by a reputable manufacturer, and that they’re certified to block out UVA and UVB at least – if they don’t do this, it’s very possible that they’re worsening your exposure to harmful light by tricking your eyes into.

Since damage from UV exposure is cumulative, it’s important to regularly wear a high-quality set of sunglasses, and to start young. If you teach your children at a young age about the value of wearing good sunglasses, you may save their eyes from damage later – and besides, everyone knows how cool a good set of shades look.
