LASIK and PRK are laser vision-correction procedures that reshape the cornea so that light focuses more accurately on the retina. They can reduce dependence on glasses or contact lenses for suitable patients, but they are not interchangeable package labels and they do not create a responsible guarantee of perfect vision. The direct answer is this: LASIK or PRK should only be considered after a full eye examination confirms that your prescription, cornea, tear film and expectations fit the procedure.
Patients comparing Turkey, the UK or any other destination often start with price and technique names. That is understandable, but the safer order is different. First comes candidacy, then the exact technique, then the written scope and cost. A discount cannot compensate for an unsuitable cornea, uncontrolled dry eye, unstable prescription or missing follow-up plan.
Who is usually assessed for LASIK or PRK?
A typical assessment looks at age, stable refraction, corneal thickness, corneal topography, pupil size, tear film, eye pressure, retina, general health, medicines, pregnancy or breastfeeding status, previous eye surgery, contact-lens history and visual priorities. The direct answer is that a glasses prescription alone is not enough to decide suitability. Two people with the same prescription can receive different advice if one has thin corneas, dry eye symptoms, keratoconus risk or work that depends heavily on night driving.
Contact lenses may need to be stopped before measurements, because they can temporarily alter corneal shape. The exact period depends on lens type and the clinician's protocol. If a provider offers a final recommendation without reliable measurements, that is a reason to pause.
LASIK and PRK are different in the cornea
LASIK creates a flap in the cornea and reshapes tissue underneath it. PRK treats the surface after the outer epithelial layer is removed or moved aside, and that surface layer then heals. The direct answer is that LASIK often has faster early visual recovery, while PRK usually has more early discomfort and a slower return of sharp vision.
PRK may be discussed when flap creation is less desirable, such as in some thinner corneas or certain lifestyle situations, but it is not automatically safer for every patient. LASIK has flap-related considerations. PRK has surface-healing considerations, including discomfort, light sensitivity, haze risk and more delayed visual stability. The better choice is the one supported by measurements and a clinician's explanation, not the one with the most modern-sounding advertisement.
Dry eye can change both suitability and recovery
Dry eye is one of the most common concerns after laser vision correction. The direct answer is that existing dry eye should be assessed and treated before deciding on LASIK or PRK, because surgery can worsen symptoms or make recovery more uncomfortable. Symptoms can include burning, gritty sensation, fluctuating vision, watering, redness and contact-lens intolerance.
A proper evaluation should include symptom history and tear-film assessment. Patients who already need lubricating drops, have autoimmune disease, take medicines that dry the eyes, work long hours on screens or struggle with contact lenses should raise this early. Some dryness improves over weeks or months, but no provider should promise that dry eye will not happen or will always be temporary.
Night vision, halos and glare deserve a direct discussion
The direct answer is that halos, glare, starbursts, reduced contrast and difficulty with night driving can occur after LASIK or PRK, even when the eye reads well on a vision chart. These symptoms may be temporary during healing, but they can be more important for patients who drive at night, work under bright lights, fly, operate machinery or already notice glare with glasses or contact lenses.
Pupil size, prescription strength, treatment zone, corneal shape, tear quality and healing can influence night-vision quality. A responsible consultation does not simply say "you will see 20/20". It explains visual quality: contrast, comfort, night driving, dim-light performance and what to do if symptoms persist.
Will I still need glasses after LASIK or PRK?
The direct answer is yes, you may still need glasses or contact lenses for some tasks after LASIK or PRK. Undercorrection, overcorrection, regression, astigmatism, age-related reading vision and personal visual demands can all affect the result. Laser correction for distance vision does not stop presbyopia, the normal age-related loss of near focusing.
If you are in your late thirties or forties, ask specifically about reading vision. Some patients prefer both eyes targeted for distance and later use reading glasses. Others ask about monovision, where one eye is adjusted differently for near tasks, but that requires careful trial and counselling because not everyone adapts comfortably.
How painful is recovery and when can I travel?
The direct answer is that LASIK is often associated with mild early discomfort and faster early vision, while PRK commonly causes more soreness, watering, light sensitivity and blurred vision for the first days as the surface heals. Recovery instructions vary, but both procedures require drops, eye protection, hygiene precautions and follow-up.
Do not plan travel around the marketing promise of a "same-day" procedure. Ask when the first review occurs, when flying is acceptable, how long to avoid swimming and eye make-up, what to do about screens, and who handles urgent symptoms if you return home. Severe pain, worsening vision, increasing redness, discharge or sudden new visual symptoms need urgent eye-care advice, not reassurance from a sales message.
What should be included in a written plan?
A useful written plan names the clinic, surgeon or responsible clinician, procedure type, laser platform, preoperative tests, treatment target, medicines, follow-up schedule, exclusions, enhancement policy and urgent contact route. The direct answer is that a quote should explain the clinical scope, not only the price.
Ask whether both eyes are treated on the same day, what happens if measurements change, how dry eye is managed, and whether there are extra costs for reviews or enhancement. If the answer to every concern is "no problem", keep asking. Good refractive surgery counselling is specific about trade-offs.
What is Just Clinic Istanbul's role?
Just Clinic Istanbul is an independent marketing and lead generation platform, not a healthcare provider or medical tourism intermediary. Enquiries may be shared with authorised healthcare partners with your consent. The platform can help you request written information and compare the scope of a proposed plan, but it cannot examine your eyes, decide whether LASIK or PRK is suitable, select a technique or guarantee a visual result.
The direct answer for anxious patients is simple: do not commit to LASIK or PRK until an ophthalmic clinician has explained why your own eyes are suitable, what could go wrong, how follow-up works and what visual compromises may remain.
