Ophthalmology & LASIC

Ophthalmology is the branch of medicine that deals with the anatomy, physiology and diseases of the eyeball and orbit.

Diseases:

  • Refractive error including near-sightedness, far-sightedness, etc.
  • Cataract
  • Glaucoma
  • Macular degeneration
  • Diabetic retinopathy
  • Dry eyes
  • Strabismus (misalignment/deviation of eyes)
  • Proptosis (bulged eyes)
  • Excessive tearing (nasolacrimal duct obstruction)
  • Uveitis
  • Eye tumors

Eye examination:

  • Visual acuity
  • Refraction
  • Intraocular pressure measurement
  • Slit lamp exmination
  • Retina examination

Specialized tests:

  • Optical coherence tomography
  • Fluorescein angiography
  • Ultrasonography

Subspecialties:

  • Anterior segment surgery
  • Cornea, ocular surface, and external disease
  • Glaucoma
  • Medical retina, deals with treatment of retinal problems through non-surgical means.
  • Vitreo-retinal surgery, deals with surgical management of retinal and posterior segment diseases and disorders. Medical retina and vitreo-retinal surgery sometimes together called posterior segment subspecialisation.
  • Neuro-ophthalmology
  • Ocular oncology
  • Oculoplastics and orbit surgery
  • Ophthalmic pathology
  • Pediatric ophthalmology/strabismus (misalignment of the eyes)
  • Refractive surgery
  • Uveitis
  • Veterinary specialty training programs in veterinary ophthalmology exist in some countries.

LASIK

LASIK commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism. The LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most people, LASIK provides a long-lasting alternative to eyeglasses or contact lenses.

LASIK is most similar to another surgical corrective procedure, photorefractive keratectomy (PRK), and LASEK. All represent advances over radial keratotomy in the surgical treatment of refractive errors of vision. For patients with moderate to high myopia or thin corneas which cannot be treated with LASIK and PRK, the phakic intraocular lens is an alternative.

Effectiveness:

Photorefractive (laser) surgery for the correction of refractive errors is safe and efficacious for use in appropriately selected patients.

Surveys of LASIK surgery find rates of patient satisfaction between 92 and 98 percent.
