What is ICL Surgery?
ICL (Implantable Collamer Lens) surgery is an advanced refractive procedure that offers a life-changing solution for vision correction. It involves implanting a thin, biocompatible lens inside the eye, which works in harmony with your eye's natural focusing system to provide clear, high-definition vision. Unlike laser surgeries that reshape the cornea, ICL is an additive procedure that preserves corneal tissue and is completely reversible.
Conditions Corrected by ICL Surgery
ICL surgery is a versatile and effective solution for a wide range of refractive errors, particularly those that may not be suitable for laser vision correction. It is designed to treat:
-
High Myopia (Nearsightedness): ICLs can correct a much broader and higher range of nearsightedness than laser procedures.
-
Astigmatism: Toric ICLs are available to correct astigmatism, often in combination with myopia.
ICL Surgery Procedures
-
Procedure Duration & Anesthesia
-
The surgery is relatively quick, usually taking 10 to 20 minutes per eye. Anesthesia is typically a local anesthetic, such as numbing eye drops, to ensure a comfortable and pain-free experience. A mild sedative may also be offered to help you relax.
-
-
Pain During Surgery
-
Most patients report feeling little to no pain during the procedure. While you may feel a slight pressure or touch sensation, the use of numbing eye drops ensures a comfortable experience.
-
-
Post-Surgery Vision & Precautions
-
Vision: Many patients experience an immediate, significant improvement in vision. It may be slightly blurry at first, but it typically clears within a few days.
-
Precautions: You will be given protective eye shields to wear, especially at night, for the first week. It is crucial to follow your surgeon's instructions to avoid rubbing your eyes, strenuous exercise, swimming, or hot tubs for a specified period.
-
Risks of ICL Surgery
While ICL surgery has a very high safety profile, as with any medical procedure, there are potential risks and complications. Your surgeon will discuss these with you in detail.
-
Detailed Potential Risks
-
Over/Under Correction: Residual refractive error can occur if the ICL power was not perfectly calculated or if the eye's healing affects the outcome. This can sometimes be managed with glasses, contact lenses, or, in some cases, an ICL exchange.
-
Cataract Formation: While rare with modern ICL designs, there is a small risk of cataract formation if the ICL touches the natural lens.
-
Elevated Intraocular Pressure (IOP): IOP can temporarily increase after surgery. This is usually managed with medication but, if persistent, may require intervention.
-
Infection (Endophthalmitis): An extremely rare but serious complication.
-
Halos and Glare: Some patients may experience halos or glare around lights, especially at night. This often diminishes over time as the brain adapts.
-
Lens Malposition or Rotation: The ICL may shift or rotate, causing blurred vision. This can often be corrected with a simple repositioning procedure.
-
Persistent Elevated IOP / Glaucoma: Long-term IOP elevation can occur due to various factors, including pupillary block (rare with modern ICLs), pigment dispersion, or steroid response. If persistent, it can lead to glaucoma and require medication, laser, or ICL removal/exchange.
-
Endothelial Cell Loss: The endothelium is a vital layer of cells on the inner surface of the cornea. A healthy endothelial cell count is crucial for corneal clarity. While ICLs are designed to maintain a healthy vault (distance from the endothelium), insufficient vault or chronic inflammation can, in rare cases, lead to accelerated endothelial cell loss, potentially affecting corneal health in the long term.

Cost of ICL Surgery in Japan
ICL surgery in Japan is generally considered an out-of-pocket expense for international patients and is not covered by Japan's public health insurance. The cost varies based on the type of IOL used, the clinic, and the surgeon's expertise.
-
Estimated Costs (Both Eyes).
-
For both eyes, the cost of ICL surgery in Japan generally ranges from approximately 800,000 to 1,000,000 JPY.

(Approx.: ~$5,120 - $6,400 USD / ¥36,800 - ¥46,000 CNY / ₱296,000 - ₱370,000 PHP / ₹424,000 - ₹530,000 INR / Rp83,600,000 - Rp104,500,000 IDR / ฿184,000 - ฿230,000 THB)

Advantages of ICL Surgery in Japan
-
Hole ICL: A Japanese Innovation in ICL
-
The V4c Model, also known as the Hole ICL, is a unique and advanced type of Implantable Collamer Lens pioneered in Japan. This innovation features a tiny central hole that promotes the natural flow of fluid inside the eye, eliminating the need for an additional laser procedure. This leads to enhanced safety, reduced procedure time, and a more comfortable overall experience for the patient.
