Many people experience a syndrome known as dry eye for a short time after undergoing LASIK surgery. However, some patients may suffer from long-term chronic dry eye, which can cause pain and irritation that eye drops fail to relieve.
Scientists from the Schepens Eye Research Institute have now found that post-LASIK chronic dry eye may be predictable in some patients, based on symptoms before the procedure takes place. While a person may not realize that they have a relatively low level of tear production, an ophthalmologist may be able to identify this and offer preventative pretreatment.
Researchers plan to expand their tests to another vision-correcting surgery called PRK, or photorefractive keratectomy, which often produces the same side effects as LASIK.
