In ophthalmology, when considering vision correction alternatives for a patient with myopic astigmatism, especially a young patient who does not prefer spectacles, multiple options exist. Here, we evaluate the alternatives provided:
1. Spherical Specs: This option is merely another form of spectacles, which the patient does not want. Thus, it’s not suitable.
2. FEMTO Lasik: This procedure reshapes the cornea to correct refractive errors. Although effective, it is generally not recommended for patients under 18 due to potential changes in the eye as they mature.
3. LASIK: Similar to FEMTO Lasik, LASIK also involves corneal reshaping and shares the age-related contraindications, making it less suitable for a 15-year-old.
4. ICL (Implantable Collamer Lens): This is a surgical procedure involving the implantation of a lens inside the eye, sitting in front of the natural lens. It is reversible, less age-restricted compared to LASIK, and particularly suitable for those not wanting or not eligible for refractive surgery, such as younger patients or those with unstable vision due to age.
Given these considerations, the best alternative for a 15-year-old patient who doesn't want to use spectacles for myopic astigmatism is:
