High Myopia Treatments (ICL & Phakic Lens)
Treating high myopia not only improves your quality of vision, but also helps protect your long-term eye health. Clinically, we offer our high myopia patients personalized treatment options using the most advanced technologies available.

High Myopia: What You Need to Know
High myopia is an advanced form of myopia — commonly known as nearsightedness — in which vision cannot be adequately corrected with standard glasses or contact lenses alone, and stronger corrective treatments may be required. High myopia is defined as a refractive error exceeding -6.00 diopters and can significantly affect your quality of vision in daily life.
High myopia also carries additional risk factors that can threaten long-term eye health:
-
Risk of retinal detachment
-
Risk of glaucoma (elevated intraocular pressure)
-
Macular degeneration
-
Cataract development
What Are the Symptoms of High Myopia?
Symptoms of high myopia include:
-
Blurred distance vision
-
Difficulty seeing at night
-
Headaches and eye strain
-
Light scattering or shadows in your vision
If you are experiencing one or more of these symptoms, a comprehensive eye examination is important to evaluate treatment options for high myopia. A personalised treatment plan is developed based on each patient's individual needs.
High Myopia Treatment Options
For the treatment of high myopia, different approaches may be recommended depending on the structure of your eye and the degree of myopia. The treatment options we offer include:
- Laser Treatment
Excimer and femtosecond laser technologies reshape the cornea to allow light to focus correctly on the retina. Laser treatment is most effective for mild to moderate myopia, but can also be considered for high myopia in certain cases. Procedures such as LASIK, PRK, and SMILE can achieve successful outcomes depending on the degree of myopia. -
Phakic Intraocular Lenses (ICL)
Phakic intraocular lenses offer an effective solution for eliminating the need for glasses or contact lenses in patients with high myopia. These lenses are placed in front of the eye's natural crystalline lens, providing a permanent solution for high myopia patients who are not suitable candidates for laser treatment. Phakic lenses can be removed if necessary and do not damage the structure of the eye. -
Refractive Lens Exchange (RLE)
RLE involves replacing the eye's natural lens with an artificial one. It is generally preferred in older patients with high myopia, particularly when additional refractive errors such as astigmatism are present. This approach can significantly improve visual quality in high myopia. -
Intrastromal Corneal Ring Segments (ICRS)
Intrastromal corneal ring segments are small, crescent-shaped implants used to alter the shape of the cornea. Inserted into the corneal tissue, these rings can be effective in treating high myopia — particularly in patients with keratoconus, where corneal thinning is present. By flattening the cornea, this treatment reduces the degree of myopia and improves visual quality.
Personalized High Myopia Treatment
The clinic develops personalized treatment plans for each patient, tailored to their eye anatomy, degree of myopia, and lifestyle. Every individual's needs differ when it comes to high myopia treatment — which is why, following a thorough eye examination, we provide a treatment recommendation specific to you. This approach is designed to achieve the highest level of patient satisfaction.
Devices and Technologies Used in High Myopia Treatment
Using advanced technology, we achieve fast and reliable outcomes in high myopia treatment. As a clinic, we are equipped with the most modern devices to deliver high-quality care to our patients. The key devices and technologies we use include:
-
Excimer and Femtosecond Laser Systems: Laser technologies used to reshape the cornea in cases of high myopia.
-
Phakic Intraocular Lens Implantation Devices: Systems that enable safe lens implantation for patients with advanced myopia.
-
Femtosecond Laser for Corneal Ring Segments: Devices that create precise channels in the cornea to allow accurate placement of ring segments.
-
High-Resolution Imaging Technologies: Imaging systems that provide detailed analysis of the structure of the retina and cornea.
Through these technologies, delivering the best possible outcomes for our patients and preserving their eye health remain our highest priorities.
Life After High Myopia Treatment
Treatment for high myopia typically leads to a significant improvement in visual quality. There are several important points to keep in mind throughout the treatment process:
-
Recovery Process: Following your doctor's recommendations after procedures such as laser surgery or lens implantation will help accelerate recovery.
-
Eye Hygiene: Keeping your eyes clean and maintaining good hand hygiene reduces the risk of infection.
-
Regular Eye Examinations: After myopia treatment, it is advisable to continue protecting your eye health through regular follow-up examinations.
