Is there any limit power range for LASIK surgery for eye?

It is not correct as treatment of power more than -8.0 leads to excessive flattening of the cornea and resultant disturbances in a vision called a spherical aberration. It is therefore recommended that the ideal upper limit is -8.0, while the acceptable upper limit is -10.0.

Can I get PRK If I have a cold?

Can you get PRK with astigmatism?

Two laser surgeries that can treat astigmatism are LASIK (laser-assisted in situ keratomileusis) and PRK (photorefractive keratectomy). LASIK - clear vision without contacts or glasses!

Is PRK worth the risk?

However, when PRK is performed by an experienced surgeon, the risk of complications is quite low. In fact, this surgery is among the safest procedures today when performed properly. One advantage of PRK over LASIK is that there is no risk of flap complications because no corneal flap is created.

Can anyone PRK?

Patients considering PRK must be at least 18 years old. Your vision should also be stable for at least one year before undergoing this procedure. Additionally, candidates should: Not currently be taking steroids or certain medications such as Cordarone®, Accutane®, or Imitrex®

Can I get PRK If I have keratoconus?

If you have keratoconus (even mild keratoconus), laser eye surgeons will discourage you from having laser vision correction. Procedures like LASIK and PRK reshape the cornea by removing microscopic particles of tissue.

How many diopters can PRK correct?

With PRK, the following refractive errors can be corrected: In Myopia, or nearsightedness, up to –8.0 Diopters can be corrected. In Astigmatism, up to 5.0 Diopters can be corrected.

Is it OK to watch TV after PRK?

In the first 24 hours after PRK, it's important that patients avoid any activities that may result in eyestrain. This includes reading, using the computer, watching TV or movies, and so forth. By resting your eyes for the first day, you will improve your overall healing experience.

How much cornea is removed in PRK?

The flap in LASIK is typically about 20% of the corneal thickness, leaving 80% of the corneal tissue to work with. In PRK, the surface layer of cells that is removed is less than 10% of the corneal thickness, leaving more available tissue to work with. Thus, PRK can be the only option for patients with thin corneas.

How painful is PRK?

According to Adler, the surgery itself is painless because of the numbing eye drops, but once the effect of the drops wears off, you may start to feel some discomfort. This sometimes feels like a scratch on the eye and lasts for about four days after the surgery.

What is the max eye power?

20/10 vision is thought to be the maximum visual acuity of human eyes without binoculars or other magnifying devices. Recent advances in optics have led to the creation of corrective lenses that can provide this ultra-sharp vision.

What prescription is too high for laser eye surgery?

Normally, traditional Laser Eye Surgery can only correct prescriptions up to a maximum of between -8 and -10. This is because in traditional Laser Eye Surgery, the surgeon cuts a circular flap from the surface of the cornea and removes tissue from the exposed cornea, reshaping it to remove refractive errors.
