Cataract Surgery’s Impact on Age-Related Macular Degeneration Remains Blurry
by: Caitlyn Fitzpatrick
Physicians have speculated about the connection between cataract surgery and age-related macular degeneration (AMD). Some findings on this topic indicated that the surgery leads to AMD’s progression; however, cold hard facts are absent.
Cataract surgery techniques have gotten better and better over the years. Many patients experience improved visual acuity after the procedure. However, replacing the cloudy lens inside the eye with an artificial one may impact someone with AMD or diabetic retinopathy. Lines on potential results of cataract surgery get even blurrier when considering patients with early and late stage disease as well as whether they have wet or dry AMD.
But the one thing known for sure is that data on cataract surgery and AMD is inconsistent.
Researchers from South Korea looked at an Asian population, who especially lack data on the matter. The cohort consisted of 17,987 people ages 40 and over and genders were split nearly in half.
“The association between cataract surgery and AMD was assessed in each right and left eye using logistic regression models in both eyes using generalized estimating equation models,” the authors explained in JAMA Ophthalmology. …..
