The environment wherein we live is made up of billions of objects, each with its own color and sharpness. Those with good vision have the luxury of seeing all of these things, which is a blessing.
This could be due to visual impairment or hazy and poor vision. Lasik Surgery and Cataract Surgery are two well-known treatments for treating vision problems in people.
Key Takeaways
- LASIK surgery corrects refractive errors in the eye, like nearsightedness, farsightedness, and astigmatism.
- Cataract surgery involves removing the clouded lens in the eye and replacing it with an artificial lens.
- LASIK reshapes the cornea, whereas cataract surgery focuses on the eye’s lens, addressing different eye problems.
Lasik Surgery vs Cataract Surgery
LASIK (Laser-Assisted in Situ Keratomileusis) is a type of eye surgery that utilizes a laser to reshape the cornea, which can improve and correct vision. Cataract surgery is also eye surgery, but it involves removing the cloudy lens from the eye and replacing it with an artificial one.

Lasik Surgery, also known by various names such as Laser eye surgery or Laser vision surgery, seeks to improve an eye’s vision.
Cataract Surgery, on the other hand, removes the extra cataract from one’s eye and allows the person to see things clearly. It’s also known as lens replacement surgery since it tries to replace the natural lens in the eye with an artificial lens. This artificial lens is made with acrylic in order to improve efficacy.
