LASIK eye surgery is a tried and true procedure that offers many the ability to ditch glasses and contact lens for good with minimal downsides. However, not everyone qualifies as a good candidate for LASIK eye surgery. 


For any questions on the right eye care procedure for you, consult the eye experts at Universal Vision Medical Center with the advanced technology and skillful hands of Orange County’s most trusted ophthalmologist, Farnoosh Tinoosh M.D.

Reasons to Consider LASIK Eye Surgery 

LASIK is a refractive eye surgery that aims to reshape the cornea in order for light to focus evenly in the retina, correcting vision. Blurred vision is caused by a refractive error that can stem from the three following cases. 


  • Nearsightedness (myopia) – This occurs when the shape of the cornea is excessively curved, causing light to focus in front of the retina making objects nearby appear clear, but farther objects become blurry.


  • Farsightedness (Hyperopia) – This occurs when the shape of the cornea is excessively flat, causing light to focus behind the retina making farther objects appear clear, while nearby objects become blurry. 


  • Astigmatism – This occurs when the shape of the cornea is unevenly flat or curved, causing overall blurred vision. 

Pre-existing Conditions 

Prior to LASIK eye surgery, the eye surgeon will perform a detailed evaluation of your overall eye health to determine the best plan of action for your case. There are certain pre-existing conditions and diseases that may disqualify you as a potential candidate for LASIK eye surgery. 


  • Certain eye injuries 
  • Abnormally large pupils 
  • Eye inflammation or infections
  • Glaucoma, cataracts, or dry eye. 
  • Progressive degenerative eye condition that runs in the family. 


An evaluation of pre-existing condition isn’t only limited to conditions or diseases related to eye health, but also related to the LASIK candidate’s overall health as well. 


  • Disease or condition that compromises the immune system.
  • Advise your eye surgeon if you take immunosuppressive medication. 
  • Uncontrolled diabetes, which can greatly increase the risk of complications.  


It is ultimately up to the discretion of the eye surgeon whether the patient is a good candidate for LASIK eye surgery. 

Possible Side Effects 

LASIK eye surgery is a tried and true procedure with a good track record of successful outcomes. However, it’s important to be aware of the risks associated with the procedure. 


  • Dry eye — LASIK surgery can cause a temporary decrease in tear production.
  • Vision Issues – Glare, halos, double vision, and difficulty seeing at night
  • Undercorrections or Overcorrections — Occurs when the laser removes too little or too much tissue, leaving a lack of vision clarity. 
  • Astigmatism – Can be caused by uneven tissue removal. 
  • Corneal Ectasia – A serious complication that occurs in cases of progressive myopia
  • Flap problems – Issues involving the flap removal can cause complications, including infection and excess tears. 
  • Vision loss or changes – May experience temporary loss of vision due to complications.

Key Takeaway
