My dad troubled with blurry vision

[tilliebls456]

My dad is 45 years old. He is troubled with blurred vision. His physician prescribed him to undergo cataract surgery. But he is scared to go under the knife. So he didn’t go for the checkup. Now the situation got worsened, he finds difficult to see. When I googled it, I saw about cataract LASIK surgery. I got a basic idea such as it replaces the eye's natural lens to improve the vision. Can anyone please share the risks associated with the surgery? Will this surgery harm my dad badly? Anyway, I am planning to take an appointment for him at a laser eye surgeon in Toronto for next week. Please share your suggestions and genuine replies. Please pray for him.
