For millions of people with myopia, laser refractive surgery (such as LASIK or PRK) represents the dream of saying “goodbye to glasses”. However, a significant number of patients come to our clinic frustrated after being told “you’re not suitable” at another centre. Why does this happen? Does it mean you have to resign yourself to wearing contact lenses for ever?
Not at all. At Clínica Ramírez & Gálvez, we believe in diagnostic honesty. Laser surgery is a wonderful tool, but it is not universal. Today, Dr. Javier Ramírez explains why not every eye is a candidate for laser surgery and what solution, often a superior one, modern ophthalmology offers.
Understanding Laser Surgery: It Is Corneal Surgery
To understand why you are “not suitable”, the first thing is to know what the laser does. This surgery works by reshaping the cornea (the transparent “window” of the eye) to change the way it focuses light. The laser literally polishes and removes a microscopic amount of corneal tissue to correct the prescription.
Therefore, the fundamental requirement for this surgery is a healthy, stable cornea of sufficient thickness.
The 3 Main Reasons for a “NO” to Laser Surgery ❌
If a responsible ophthalmologist tells you that you are not a candidate, it is usually for one of these three safety reasons:
- Thin Cornea: This is the most common cause. Laser surgery uses up tissue. If your cornea is naturally too thin, removing the tissue needed to correct your myopia would leave it dangerously weak, which could cause serious long-term problems.
- Very High Prescription (High Myopia): This is directly related to the above. Correcting -8 or -10 dioptres requires removing much more corneal tissue than correcting -2. If you have a very high prescription, it is very likely that laser surgery will not be safe for you, even if your cornea is not particularly thin.
- Hidden Eye Conditions: A thorough pre-operative assessment can reveal problems that rule out laser surgery, such as early keratoconus (a deformation of the cornea), severe dry eye or a prescription that is not yet stable.
The “Plan B” That Beats Plan A: Intraocular Lenses (ICL) 💡
Being told “no” to laser surgery is not the end of the road. In fact, for many patients, it is the beginning of an even better solution: phakic intraocular lenses (ICL).
- What are they? They are microscopic lenses, made from a biocompatible material, that are implanted inside the eye, between the iris and the natural lens (without replacing it). They act like a permanent, yet invisible, contact lens.
- Why are they the best alternative?
- The cornea is not touched: No tissue is removed, making it the perfect solution for thin corneas.
- They correct high prescriptions: They can safely and accurately correct very high myopia (up to -18 or more).
- It is reversible: If it were ever necessary, the lens can be removed.
- Visual quality: In cases of high myopia, the quality of vision they provide is often superior to that of laser surgery.
A Timely “No” Is a Sign of Professionalism 🌟
A surgeon telling you “no” to laser surgery is not a failure; it is an act of the utmost medical responsibility. It shows that they put your long-term safety above everything else.
Modern ophthalmology has incredible solutions for almost every case. A “no” to laser surgery is very likely a resounding “yes” to ICL lenses. If you want to know the best, safest and most effective solution for your eyes, book your appointment. At Clínica Ramírez & Gálvez we will carry out a complete assessment to give you an honest answer.
