Cataract surgery is a common procedure for correcting vision problems, and many people are curious about how changes in weather or temperature can affect their vision after the surgery. A recent study conducted in China found that extreme heat and low humidity were independently associated with a higher likelihood of developing cataracts in older adults. The study also revealed that hospitalizations for cataracts were negatively associated with extreme heat, providing useful implications for hospitals to manage medical resources in hot weather. The research examined the associations between relative air humidity and temperature with cataracts in older adults.
Bivariate comparisons showed that a statistically significant better visual outcome was related to days with lower temperatures. Patients with cataracts may be concerned that the effect of treatment on very hot days may be worse than when the weather is fine, since extreme heat could increase the risk of infection after surgical treatment. A previous study suggested that cold-related increases in sympathetic nervous activity may contribute to improved platelet function, with an increased risk of thrombosis in cold climates in essential hypertension. Eyes treated on days with a lower temperature do better after LASIK according to postoperative visual outcome, refractive index, and spherical equivalent.
The associations indicated that extreme heat and low humidity may be related to a higher incidence of cataracts in older people. Fall is the perfect time to correct your vision, right between summer and winter. However, it is important to note that your eyes may be sensitive after eye surgery, and it will take a while to get used to bright colors. In conclusion, this study found that extreme heat and low humidity were independently associated with a higher likelihood of developing cataracts in older adults.
It also provided useful implications for hospitals to manage medical resources in hot weather. Patients should be aware that their eyes may be sensitive after eye surgery, and it will take a while to get used to bright colors.
