Advanced Surface Ablation - For More Complex Laser Treatments

Advanced surface ablation can improve your quality of vision, if you:

  • Have dry eyes with your contact lens wear or have become contact lens intolerant

  • Would like to reduce the risks of contact lenses

  • Are fed up of wearing glasses

  • Are not satisfied with the quality of vision achieved with your contact lenses or glasses

  • Would like to enjoy an active lifestyle ​without the compromise of glasses

  • Have a medical condition of your cornea with irregular astigmatism, such as keratoconus 

What is Advanced Surface Ablation?

Advanced surface ablation (ASA), a variant of LASEK, can eliminate the need for glasses or contact lenses by correcting short-sightedness (myopia), long-sightedness (hypermetropia) and astigmatism.   


The visual recovery following ASA is slightly slower than with LASIK or SMILE;  it is therefore carried out when LASIK or SMILE are not indicated, such as in thin corneas or corneas with a medical condition such as keratoconus and prior scarring. 

What are the benefits of Advanced Surface Ablation?

  • An active lifestyle without the hassle of glasses or contact lenses

  • Spectacle independence

  • No contact lens risks

  • It can be applied to the correction of complex and irregular refractive prescriptions 

  • It can be combined with collagen cross-linking if you have keratoconus

Frequently asked questions

Is laser vision correction painful?

A slight pressure feeling may be noticed during the procedure but no pain. Your eyes will be gritty and sensitive to light for the first three to four days, slightly more so than following LASIK or SMILE. 

Can laser vision correction cause blindness?

 Permanent serious loss of vision following laser vision correction is extremely rare, as the procedure is not carried out inside the eye but on the outside.


Poor vision may be caused if an infection were to develop following the procedure; the risk of this occurring is approximately 1 in 10000. In the worst likely scenario, a form of corneal transplantation may be required to replace a damaged block of tissue in the cornea, restoring vision usually to driving standards. Problems that can lead to the need for transplantation include scarring after infection or an abnormal healing response, and an unstable corneal shape, also called corneal ectasia. These problems occur infrequently, and can often be corrected without transplant surgery. 

Does laser vision correction cause dry eye?

For patients with a healthy eye surface prior to the procedure, lasting dry eye symptoms are unusual. Dry eye symptoms and intermittent blurring (variable vision) can be caused by reduced stability of the tear film between blinks.


Tear film stability and dry eye symptoms improve over the first two to three months after the procedure. During this period, most patients require the use of frequent tear supplements. Contact lens wearers usually experience an improvement in dry eye symptoms compared to before the procedure!

Is laser vision correction permanent?

The effects of laser vision correction on the cornea and your vision are permanent. However, in your fifth decade of life and later the natural lens inside your eye undergoes changes that may change your prescription and need for reading glasses.

Cataract surgery with multifocal lenses


I had corrective lenses inserted in both eyes due to cataracts by Mr Aris Konstantopoulos. I am delighted with the results. After 10 years of wearing varifocal spectacles I no longer need them. Mr Konstantopoulos explained everything in detail before and during the procedure. I want hesitate to return to this consultant should I have any other problems with my vision in the future.
