ICL surgery (Implantable Collamer Lens surgery) is a method in which a special lens is inserted into the eye to correct vision, and is particularly effective for correcting myopia, astigmatism, and hyperopia.
In this article, we will explain in detail the main advantages and disadvantages of ICL surgery.
Advantages
1. High visual correction effect
ICL surgery can correct vision without removing corneal tissue, making it possible to address a wide range of myopia, hyperopia, and astigmatism, and improvement in vision can be expected.
2. Reversibility
The ICL lens can be removed at the physician’s discretion. If necessary, the lens can be replaced, or removed to return the eye to its preoperative state.
3. Less likely to cause dry eye
Unlike procedures such as LASIK that involve removing corneal tissue, ICL does not affect the shape of the cornea, and is therefore considered to have a lower risk of dry eye.
4. Long-term stability
The lens has high durability, and postoperative vision is expected to remain stable over a long period of time.
In addition, the lens itself has a function to block ultraviolet rays, protecting the eyes from UV exposure.
5. Maintains the natural structure of the eye
Because the cornea is not removed, the natural shape of the eye is preserved after surgery.
Disadvantages
1. High cost
The cost may be higher than other vision correction surgeries such as LASIK.
2. Surgical risks
Similar to LASIK, there is a possibility of infection (endophthalmitis) after ICL surgery. However, with appropriate postoperative care such as restricting eye washing and hair washing and continuing eye drops for a certain period, the likelihood is extremely rare and very low.
3. Requires regular follow-up
After surgery, regular check-ups at an ophthalmology clinic are necessary. Continuous monitoring of intraocular pressure, lens position, and intraocular health is required.
4. Not suitable for all patients
Depending on the condition of the eye or the size of the eyeball, ICL surgery may not be suitable. Preoperative examinations are required.
5. Cannot address presbyopia or age-related changes
ICL corrects myopia and hyperopia, but cannot correct presbyopia.
With aging, additional presbyopia correction or cataract surgery may be required.
Who is suitable for ICL surgery
- ・People with high myopia or astigmatism
- ・People with thin corneas who are not suitable for LASIK
- ・People concerned about dry eye
Summary
As a new option for vision correction, ICL surgery offers significant advantages, especially for people with high myopia or astigmatism. However, since it also involves costs and risks, it is important to gather sufficient information, consider your lifestyle and health condition, and consult thoroughly with a doctor before making a decision.
