What vision is too high for LASIK?

As a general rule, with cutting-edge laser technology like the equipment our team uses, LASIK has the ability to treat: Nearsightedness up to -12.00 diopters. Astigmatism up to 6 diopters. Farsightedness up to +6.00 diopters.

What if your prescription is too high for LASIK?

LASIK Alternatives

For example, if you have a high prescription, then your doctor might suggest lens surgery instead. Implantable contact lenses (ICL) are simply inserted into your eyes, with no need to operate on the cornea. This is also a good option for those with dry eyes or thin/irregular corneas.

What is the maximum limit for LASIK?

It is therefore recommended that the ideal upper limit is -8.0, while the acceptable upper limit is -10.0. Beyond this number, LASIK should be avoided, and a better way would be to go in for an ICL implant. The upper limit of correction by LASIK for a plus number, i.e. hypermetropia is +5.0.

At what point can you not get LASIK?

You have a disease or are on medications that may affect wound healing. Certain conditions, such as autoimmune diseases (e.g., lupus, rheumatoid arthritis), immunodeficiency states (e.g., HIV) and diabetes, and some medications (e.g., retinoic acid and steroids) may prevent proper healing after a refractive procedure.

Who is not a candidate for LASIK eye surgery?

Patients with autoimmune diseases are not good LASIK candidates. Many autoimmune conditions cause dry eye syndrome. A dry eye may not heal well and has a higher risk of post-LASIK infection. Other conditions such as diabetes, rheumatoid arthritis, lupus, glaucoma or cataracts often affect LASIK results.

What are the risks for a patient with a very high prescription?

Is LASIK worth it over 40?

But the answer is generally yes – LASIK is worth it after 40. LASIK is safe and effective for patients older than 40 and produces the long-term value that this refractive surgery is known for.

Can I do LASIK if my degree is high?

There is no minimum power i.e. people with 100 degrees of myopia can still go for refractive surgery. The maximum power for safe myopia correction is usually limited to 1,300 degrees. For astigmatism, we usually do not treat patients with more than 400 degrees of astigmatism.

Can LASIK bring back 20/20 vision?

In general, most people who have laser-assisted in situ keratomileusis (LASIK) eye surgery achieve 20/20 vision or better, which works well for most activities.

What prescription is too high for contacts?

The highest level of corrective power for monthly soft contact lenses is about -12 Dioptres (bear in mind that the average prescription for short sighted people is -2.00 Dioptres), and is available from both Purevision 2HD and Biofinity.

Can you get LASIK If your eyes get worse?

Yes, your vision can be potentially too bad for LASIK. LASIK is available to a variety of patients, but patients will generally qualify for treatment if their vision falls between -0.5 D to -8.0 D myopia. The maximum prescription for treatment for patients with moderate to severe myopia is around -8.0 D.

Can I do LASIK if I have high astigmatism?

For extremely high astigmatism, LASIK may be a very suitable option. LASIK surgery attempts to permanently correct cornea abnormalities. High astigmatic patients will often see improvement in their vision, but may still need to wear contact lenses or glasses to achieve the desired results for vision correction.

Is LASIK worth it for high myopia?

Because people with severe myopia are at higher risk for conditions like glaucoma and retinal detachment, many surgeons will not perform LASIK on these patients. LASIK surgery is safe for people who are at low risk for other eye conditions, but not for those who are already at risk.

What is the highest eye prescription?

What is the highest prescription for astigmatism?

What is classed as a high eye prescription?

Patients will commonly fall within the -25.00 or +25.00 range and the majority between +4.00 or -4.00. For those considered to have high prescriptions, those over +/- 4.00, we might also need a 'back vertex distance' (BVD), which is a millimetre measurement from the back of the lens to the front surface of the eye.

Can LASIK fix 20 200?

This is also known as tunnel vision. On the other hand, many patients consider themselves “legally blind” if they see worse than 20/200 without glasses. Very often these patients are good candidates and can see 20/20 without glasses following LASIK.

Why am I still blurry 3 weeks after LASIK?

However, you may still experience blurry vision or vision fluctuations from time to time as you heal. Your eyes are adjusting to the newly reshaped cornea. They need time to get used to functioning in a new way. It will take anywhere from three to six months for your eyes to fully heal.

Why do I have blurry vision 2 years after LASIK?

However, in a small number of people, the lens may undergo age-related changes. Such changes may cause a person to develop blurry vision after a few years of LASIK surgery. The following factors can cause myopia to return after the LASIK: Having high myopia (myopia above -6.00 D)

What is the oldest age for LASIK?

The good news is that there is no age limit for LASIK if your eyes are healthy. We have treated patients across a wide age range with great success, including patients in their 40s, 50s, 60s, and beyond.

What is the limit for LASIK astigmatism?

As a general rule, with cutting-edge laser technology like the equipment our team uses, LASIK has the ability to treat: Nearsightedness up to -12.00 diopters. Astigmatism up to 6 diopters. Farsightedness up to +6.00 diopters.

Does LASIK last forever?

While the effects of LASIK surgery are permanent, the benefits can decrease over time. For most patients, the results of LASIK will last a lifetime. About 10-12% of patients nationwide will need an enhancement surgery because of anatomical changes to the eye/eyes.

Is minus 7 legally blind?

The definition of legal blindness is 20/200 vision WITH correction. If you see better than 20/200 with your -7.00 on you are NOT legally blind.

Is 5.5 eyesight legally blind?

And to be deemed "legally blind," their vision must be bad enough that they meet one of two standards: They must have a visual acuity of 20/200 or less in the eye they can see out of best (while wearing corrective glasses or contacts) or have a visual field of no more than 20 degrees.

What eyesight is legally blind?

Visual acuity less than 20/200 is considered legally blind, but to actually fit the definition, the person must not be able to attain 20/200 vision even with prescription eyewear. Many people who would be legally blind without eyewear can function well in everyday life with appropriate glasses or contact lenses.

What is the highest myopia ever recorded?

The highest degree of myopia determined with retinoscopy ever published is –60.0 D and the fundus of this eye showed only 'a very small myopic crescent'.
