Myopia surgery has become increasingly common, but some individuals who underwent early corrective procedures often experience side effects such as dry eyes and glare. Ophthalmologists point out that with technological advancements in recent years, dry eyes can be alleviated through artificial tears or punctual plugs. However, for those who underwent early radial keratotomy (RK), the resulting "glare" issue remains largely unresolved with current technology.
For aesthetic and convenience reasons, the acceptance of myopia surgery has risen significantly in Taiwan. However, many who underwent early procedures still suffer from side effects, commonly including dry eyes, glare, and light sensitivity.
Regarding glare, many people, especially those driving at night, find it particularly troublesome. Doctors note that early surgical instruments were more likely to cause glare issues. For those who underwent laser surgery, wearing dark glasses or considering additional laser treatment (if residual refractive error exists) may help. However, for those who underwent radial keratotomy (RK) in the past, the glare problem remains largely unsolvable.
Dr. Lü Da-Wen, Director of Ophthalmology at Tri-Service General Hospital, stated: "Glare caused by RK is currently almost impossible to resolve because the corneal incisions create scars that scatter light, leading to glare. In contrast, glare from standard laser surgery typically fades within about three months post-operation."
As for dry eye symptoms, doctors explain that some degree of dryness is common after surgery, but most patients recover to pre-surgery levels within three to six months. However, those with pre-existing dry eye conditions or age-related tear reduction may continue to experience discomfort. Currently, artificial tears can help increase eye moisture, while punctual occlusion can reduce tear drainage.
