Does LASIK affect axial length?

The IOLMaster showed a decrease in axial length after LASIK that correlated well with theoretical ablation depth.

Does LASIK make your cornea thinner?

The IOL is calculated to correct your refractive error. There are implants to correct astigmatism and even multifocal IOLs that allow patients to see well at both distance and near. This refractive surgery allows for the correction of myopia, hyperopia, and astigmatism without altering the cornea thickness.

Does LASIK change lens or cornea?

LASIK is eye surgery that permanently changes the shape of the cornea (the clear covering on the front of the eye). It is done to improve vision and reduce a person’s need for glasses or contact lenses.

How does the axial length of the eye change?

By using a higher sampling frequency rate with measurements of axial length every 10 minutes (with the initial measurement occurring after only 2 minutes of blur exposure), we further showed that the axial length of the human eye can change in response to relatively brief periods of myopic and hyperopic defocus.

Is the axial length a risk factor for post Lasik myopic regression?

In summary, our results support that pre-operative high axial length significantly increases the risk of having myopic regression after LASIK.

Does corneal thickness change over time?

Conclusions: : Central corneal thickness statistically increases with age whereas both the degree of symmetry and enantiomorphism decrease. Finally, most characteristics of corneal thickness are age-related.

What affects corneal thickness?

Many factors can affect CCT in the general population, such as age, gender, environmental and genetic factors, and race. The Ocular Hypertension Treatment Study demonstrated a correlation between greater mean central corneal thickness and younger age, female gender, and diabetes.

Can lens be replaced after LASIK?

After cataract surgery, many people have clear distance vision without glasses, although most still need glasses for close-up work or reading. For people like you who have had LASIK surgery, providing the appropriate lens implant for cataract surgery takes additional calculations to determine the correct lens power.

What are the side effects of LASIK surgery?

Risks

• Dry eyes. LASIK surgery causes a temporary decrease in tear production.
• Glare, halos and double vision. You may have difficulty seeing at night after surgery, which usually lasts a few days to a few weeks.
• Undercorrections.
• Overcorrections.
• Astigmatism.
• Flap problems.
• Regression.
• Vision loss or changes.
