Types of Laser Vision Correction
LASIK and LASEK are two highly popular laser vision correction procedures, both designed to:
- Be great options for many individuals who want to reduce dependence on glasses or contact lenses
- Correct nearsightedness (myopia), farsightedness (hyperopia), and astigmatism by reshaping the cornea using an ultra-precise excimer laser
Why then is LASEK the laser vision correction procedure of choice for many eye surgeons across the United States, including our own Dr. Jeffrey Fischer? LASEK's gentle procedure does not require the creation of a corneal flap as LASIK does, which makes laser vision correction possible for a greater variety of people. This includes those who may not have otherwise been able to benefit from laser vision correction due to certain eye conditions and lifestyle factors.
All About LASEK
If You Are...
- Tired of the hassles of glasses and contacts
- Looking to be able to see the alarm clock at night without putting on your glasses
- Ready to play sports without depending on glasses
LASEK laser vision correction may be right for you. Dr. Fischer and our team are some of the most experienced eye care professionals in Minnesota and have performed more than 20,000 laser vision correction procedures.
Good candidates must be at least 18 years of age, have stable vision, must not be pregnant or nursing, and should have realistic expectations. Your qualifications for laser vision correction will be evaluated during a free consultation.
What is LASIK?
What happens during laser vision correction procedures?
The LASIK procedures include:
- Cutting a corneal flap using a small instrument or a laser
- Lifting back the flap so that the surgeon can access and reshape the deeper corneal tissue using a laser
- Repositioning the flap back into place
The LASEK procedures include:
- Applying a solution to the corneal surface so that the ultra-thin layer directly below may be treated
- Smoothing this thin layer before reshaping it with a laser
- Allowing the affected corneal surface cells to naturally regenerate within a few days
What are the Benefits of the "No-Flap" Laser Vision Correction?
- If you’re active, you can stay that way
LASEK’s no-flap laser vision correction procedure means no chance of complications caused by the flap dislodging due to an active lifestyle.
- Less risk if you have high astigmatism
Resurfacing only the cornea’s surface protects deeper corneal tissue. This benefits those with higher astigmatisms, who need more resurfacing to correct their vision.
- Still enjoy clear vision even if you have thin corneas
Saving deeper corneal tissue also allows those who are not good LASIK candidates due to thin corneas to still receive treatment.
- If you have dry eye, you can rest easy
LASEK’s gentle procedure protects corneal nerves that can cause dry eye if damaged.

Frequently Asked Questions About LASEK
What if I am not a good candidate for LASEK laser vision correction?
If for some reason LASEK is not appropriate for you, another vision-correction procedure, such as radial keratotomy (RK) or Automated lamellar keratoplasty (ALK) may be recommended.
If I have diabetes, can I still have LASEK surgery?
Yes, if your diabetes is under control.
How old do you have to be to have LASEK?
Ideally, patients need to be between ages 18 and 60.
Do I need to be out of my contact lenses before surgery?
Yes, for optimum results you will need to be out of your contact lenses for a specified period of time before your exam and the procedure, so your corneas can return to their normal shape.
- Soft lenses two weeks in advance
- Toric or extended wear lenses, 4 weeks
- RGP or hard lenses, 4 weeks + one week for every decade of wear
Will I feel anything during the procedure?
Anesthetic drops are used to numb the eye and keep you quite comfortable. You also have the option to take Valium before surgery to help you relax.
