After all, LASIK is a completely elective procedure where we are operating on normal, healthy eyes that simply need either glasses or contact lenses to have the best vision, says Dr. Bert.
With more recent developments in laser technology, this is less common after 6 months though symptoms can persist beyond a year in some cases. [ citation needed ] A dilute concentration of the chemotherapeutic agent, Mitomycin-C, can be applied briefly at the completion of surgery to reduce risk of hazing, although with increased risk of sicca .
Corneal cross-linking (CXL) with riboflavin (vitamin B 2) and UV-A light is a surgical treatment for corneal ectasia such as keratoconus, [2] PMD, and post-LASIK ectasia. It is used in an attempt to make the cornea stronger. According to a 2015 Cochrane review, there is insufficient evidence to determine if it is useful in keratoconus. [3]
Dry eye also occurs or becomes worse after LASIK and other refractive surgeries, in which the corneal nerves which stimulate tear secretion [4] are cut during the creation of a corneal flap. [4] Dry eye caused by these procedures usually resolves after several months, but it can be permanent.
Presbyopia is not reversed by Laser Blended Vision, which is a highly effective treatment but not a cure and as presbyopia is a progressive condition, a boost may be required some years after treatment. Typically the effects of Laser Blended Vision surgery last between 5 and 10 years and most patients are able to have an enhancement procedure ...
Kate Middleton is opening up about the long-term side effects of her cancer treatment. On Tuesday, Jan. 14, the Princess of Wales spoke with staff during a surprise visit to the Royal Marsden ...
The technology reduces side effects linked with laser procedures like LASIK and SMILE. [1] It was FDA approved in the US in 2016. The method provides measurement of 22,000 points as compared to 200 points provided by wave front-guided LASIK method. The imperfections in the cornea are recorded and then corrected using a laser.

The difference from LASIK is that the top layer of the epithelium is removed (and a bandage contact lens is used), so no flap is created. Recovery time is longer with PRK than with LASIK, though the outcome (after 3 months) is about the same (very good). More recently, customized ablation has been performed with LASIK, LASEK, and PRK.
