Clinical guides · Istanbul
Six common vision conditions explained honestly — symptoms, treatment paths, and links to the procedures our eye centre offers.
Short-sightedness — difficulty seeing distance clearly. Laser and implant options for prescriptions up to −20 D.
Long-sightedness — near vision blurs first, especially after 40. LASIK, PRK, and lens surgery options.
Irregular corneal shape causing blurred vision at all distances. Corrected with wavefront-guided laser or toric IOLs.
Age-related loss of near focus, typically from 45. Lens replacement with trifocal or EDOF IOL is the lasting fix.
Clouding of the natural lens — colours fade and glare increases. Premium IOL surgery in Istanbul, often both eyes one trip.
Progressive corneal thinning and cone shape. Cross-linking stabilises; ICL or specialist lenses when stable — not corneal laser.

Honest clinical mapping — not every condition suits every procedure. Your surgeon confirms after examination. Not sure which condition fits? Start with our blurry vision guide — match your blur pattern first.
| Condition | First-line options | When alternatives apply | Compare guides |
|---|---|---|---|
| Myopia | LASIK · SMILE Pro | High myopia or thin cornea → ICL | LASIK vs SMILE · SMILE vs ICL |
| Hyperopia | LASIK · PRK | Age 45+ with reading blur → RLE | LASIK vs RLE |
| Astigmatism | Wavefront LASIK · SMILE | Very high cylinder → Toric ICL | LASIK vs ICL |
| Presbyopia | Lens replacement (RLE) | Under 45 with distance-only blur → laser may still suit | ICL vs RLE |
| Cataracts | Phaco + premium IOL | Early lens changes in 50s may overlap with RLE discussion | Cataract guide |
| Keratoconus | No LASIK / SMILE | Stable after CXL → ICL; specialist lenses meanwhile | Astigmatism vs KC |

Condition guides
Detailed guides for each condition — typical suitability ranges, procedure links, and when alternatives apply.
Difficulty seeing distance clearly — road signs, cinema screens, the board at work. Often diagnosed in childhood; stabilises in the early 20s.
Near tasks blur first — reading, phone screens — especially after 40 when presbyopia adds. Distance may stay acceptable until later.
Cornea shaped more like a rugby ball than a football — blurred or ghosted vision at all distances. Often combined with myopia or hyperopia.
Arm's-length reading fails from the mid-40s — the natural lens stiffens. Reading glasses, varifocals, or lens replacement are the practical options.
Clouding of the natural lens — dull colours, glare at night, frequent prescription changes. Surgery replaces the clouded lens with a clear artificial IOL.
Progressive corneal thinning and cone formation. LASIK is contraindicated; cross-linking stabilises, then ICL or surface laser may be options when stable.
