LASIK

What LASIK Does

In a shortsighted, longsighted or astigmatic eye, light focuses in front of, behind, or unevenly on the retina because the cornea and lens bend it imperfectly. LASIK (Laser-Assisted In Situ Keratomileusis) permanently reshapes the cornea's surface so that light lands where it should. A thin flap is created in the cornea, the excimer laser removes a precisely calculated amount of tissue beneath it, and the flap is laid back — healing naturally without stitches.

The laser treatment itself takes seconds per eye. Most patients notice dramatically clearer vision by the next morning.

Who May Be Suitable

Broadly, suitable candidates are adults (typically 18 or older) with a stable glasses prescription for at least a year, healthy corneas of adequate thickness and regular shape, a prescription within the treatable range, healthy eyes otherwise, and realistic expectations. Pregnancy and breastfeeding are paused periods, as hormones temporarily shift the prescription.

Who May Not Be Suitable

LASIK is not for every eye, and a responsible surgeon says so. Thin or irregular corneas, keratoconus or its early forms, unstable prescriptions, very high powers beyond safe limits, significant dry eye, certain autoimmune conditions, and unrealistic expectations are all reasons to advise against LASIK — often with PRK or ICL as the better path, or with advice to keep glasses.

Being told "no" is a good outcome of a proper evaluation: it means the screening is doing its job.

The Evaluation: More Than Your Glasses Power

LASIK eligibility is decided by your eye evaluation, not just your glasses power. The work-up includes corneal topography and tomography (mapping shape and ruling out keratoconus), pachymetry (corneal thickness), tear-film and dry-eye assessment, pupil measurement, a dilated retinal examination, and a stable refraction. Only when all of these align is surgery scheduled.

LASIK, PRK and ICL — How They Compare

LASIK offers the fastest recovery and is the first choice for many suitable eyes. PRK treats the corneal surface without a flap — slower, more uncomfortable recovery, but preferred for thinner corneas or contact-sport lifestyles. ICL places a micro-thin lens inside the eye without removing corneal tissue — the option of choice for very high powers and thin corneas, and it is reversible. Your evaluation determines which procedure, if any, fits your eyes.

Risks, Stated Honestly

LASIK is among the most studied elective procedures in medicine, and most patients are delighted. It still has risks: dry eye (usually temporary), night-time halos and glare (usually settling over months), under- or over-correction sometimes needing enhancement, and rare flap or healing complications. A small percentage of patients still need thin glasses for some tasks. You should hear all of this before deciding — and you will, here.

Recovery

Vision is usually functional within 24 hours and sharpens over days to weeks. Drops are used for a few weeks; rubbing the eyes is avoided early on; swimming and eye makeup pause briefly. Follow-up visits track healing. Most people return to desk work within a couple of days.

Understanding the diagnosis

A diagnosis of LASIK can raise practical questions about symptoms, tests, treatment and recovery. A careful consultation begins with your story: what you have noticed, how quickly it appeared, whether one or both eyes are involved, and whether conditions such as diabetes, blood pressure, previous surgery or injury may affect the eye. The aim is not to rush to a procedure. It is to understand the health of the whole eye and explain which findings matter most for your vision.

Symptoms and when to seek help

Some eye conditions develop slowly and may be noticed only during a routine examination. Others can cause a sudden change in sight. New flashes, a sudden shower of floaters, a curtain or shadow, sudden loss of vision, severe pain, marked redness after injury or rapidly worsening symptoms should be treated as urgent concerns. Routine appointments are appropriate for stable symptoms, but waiting is not a substitute for evaluation when vision changes quickly.

How the consultation works

Your visit is structured around a detailed history and an examination of each eye. Depending on the concern, this can include refraction, eye pressure measurement, slit-lamp examination, dilated retinal examination, retinal photography, OCT, visual fields, biometry, corneal mapping or other tests. Not every patient needs every test. The reason for each test should be clear, and you should have time to ask what the result means for your own situation.

Why measurements matter

Treatment decisions in vision correction and refractive care depend on measurements as well as symptoms. Two people with similar glasses powers or similar complaints may have very different corneal, lens, retinal or optic-nerve findings. Good planning therefore combines examination findings, imaging, medical history, work demands, family history and personal priorities. Measurements are useful when they lead to a safer, more individualised decision rather than being treated as a sales promise.

Treatment options are individual

There may be more than one reasonable way to manage LASIK. Options can include observation with scheduled monitoring, medicines, laser treatment, injections, glasses, contact lenses or surgery. The right option depends on the stage of disease, the health of the other eye, your general health, likely benefits, possible risks, cost, recovery requirements and how urgently treatment is needed. A consultation should explain alternatives, not only the most intensive intervention.

Preparing for an appointment

Bring previous eye reports, scans, prescriptions, medication lists and details of any diabetes, hypertension or other long-term condition. If you use contact lenses, ask whether they should be removed before measurements. Dilating drops can temporarily blur near vision and make bright light uncomfortable, so arrange transport if your clinician advises dilation. Write down your main questions. Clear questions help you and the clinical team use the appointment well.

What recovery may involve

Recovery varies by diagnosis and treatment. Some visits involve no downtime, while others require drops, activity restrictions, protective eyewear or several follow-up examinations. It is important to use medicines exactly as prescribed, avoid rubbing the eye, attend reviews and contact the clinic if pain, redness, discharge or vision changes are unexpected. Do not compare your recovery with someone else’s; the treatment and the eye are personal.

Long-term monitoring

Many eye conditions are managed over time rather than solved in one visit. Follow-up allows the doctor to compare vision, pressure, scans and symptoms with earlier findings. Keep a record of appointments and medicines, and tell the clinic about changes in general health. People living with diabetes or blood-pressure problems should continue their regular medical care because systemic health and eye health are closely connected.

Questions to ask your doctor

Useful questions include: What exactly did the examination show? What is the goal of treatment? What happens if we monitor for now? Which alternatives apply to my eye? What are the common and serious risks? How many follow-ups will I need? Which symptoms should prompt an urgent call? What should I avoid during recovery? A good decision is one you understand and can follow safely.

A patient-first approach

At Sentra Clinic & Hospital, the emphasis is on a calm explanation, appropriate investigations and a plan that fits the patient. The website cannot diagnose an eye condition, confirm eligibility for surgery or predict an individual result. Those decisions require an in-person examination. Educational information can help you prepare, but it should support—not replace—the conversation with a qualified eye specialist.
