High Myopia Treatments (ICL & Phakic Lens)
High myopia (above -6.00 diopters) can be corrected with personalized methods such as laser, phakic intraocular lenses (ICL), refractive lens exchange, and corneal rings. High myopia also requires regular follow-up for retinal and overall eye health.

Quick Answer
In high myopia, values above -6.00 diopters are corrected with laser if the corneal structure is suitable, or with a phakic intraocular lens (ICL) or refractive lens exchange if it is not. The method is determined individually through examination.
What Is High Myopia?
High myopia is a more advanced level of myopia, known as the inability to see distant objects clearly (values above -6.00 diopters). This condition can increase the risk of retinal detachment, glaucoma, macular degeneration, and cataract development.
Symptoms
- Inability to see distant objects clearly
- Difficulty with night vision
- Headaches and eye strain
- Seeing glare or shadows
Treatment Methods
- Laser treatment: The cornea is reshaped using excimer and femtosecond laser technologies so that light is focused properly onto the retina.
- Phakic intraocular lenses (ICL): Lenses placed in front of the eye’s natural lens provide a permanent solution for high myopia patients not suitable for laser treatment; they can be removed when necessary.
- Refractive lens exchange (RLE): The natural lens is replaced with an artificial lens; preferred in older patients and in cases with additional refractive errors.
- Corneal rings (ICRS): Crescent-shaped implants placed in the corneal tissue to change the shape of the cornea, reducing the degree of myopia.
Which method is appropriate is determined individually, taking into account the corneal structure and the degree of myopia.
Frequently Asked Questions
-
Can high myopia be treated with laser?
Laser can be applied in cases with a certain degree; phakic lenses (ICL) are preferred in advanced cases.
-
Are glasses needed after treatment?
In general, the need for glasses is greatly reduced; however, low-power glasses may be needed in very advanced cases.
-
Can phakic lenses be removed?
Yes, they can be removed when necessary.

Implantable Contact Lens (ICL)
ICL is a special lens placed inside the eye; it corrects high myopia and astigmatism without intervening in the corneal tissue. In keratoconus patients, it can be applied to improve visual quality once the disease has stabilized.

Laser Refractive Surgery
Laser refractive surgery is a surgical treatment method based on reshaping the cornea with a laser to correct vision disorders such as myopia, hyperopia, and astigmatism. LASIK, iLASIK, PRK, and SMILE techniques are applied following a personalized evaluation.

Cataract – Intraocular Lens Treatments
Cataract is a disease that occurs when the eye's natural lens loses its transparency. In modern refractive cataract surgery, intraocular lenses (monofocal, EDOF, trifocal, toric) are selected based on the patient's age, corneal structure, and visual needs.
