The patient is 15 years old with myopic astigmatism who refuses spectacles.
Key age restriction: LASIK (including FEMTO-LASIK) is approved only for patients 18 years or older with a stable refraction. A 15-year-old has an actively changing prescription, making laser ablation unsafe and unreliable.
ICL (Implantable Collamer Lens) is the best alternative because:
- It is a phakic IOL placed between the iris and the natural lens
- It corrects myopia, hyperopia, and astigmatism over a wide dioptre range
- The procedure is reversible -- if refraction changes, the lens can be exchanged
- It preserves natural accommodation
- No minimum age restriction applies as strictly as for laser surgery
Spherical specs would not correct the astigmatic component effectively.
