Myopia cannot be reversed naturally because the physical elongation of the eyeball that causes it does not shrink back on its own. However, the resulting blurry vision can be permanently corrected through laser refractive surgery LASIK, SMILE, or SILK or through ICL implantation. In children, progression can be significantly slowed using myopia control therapies, though these do not eliminate existing nearsightedness.
“Doctor, will my number always stay like this or is there a permanent cure?” This is the single most common question our ophthalmologists at MediVision Eye Care Centre, KPHB Colony, Kukatpally receive from patients every day. Whether it is a concerned parent in Hyderabad watching their child’s spectacle power increase year after year, or an IT professional tired of glasses after two decades, the desire for a definitive answer is universal.
The medically accurate answer is nuanced. In this article, our specialists at MediVision Kukatpally break down exactly what current science says what can genuinely be done, what common myths patients believe, the surgical options available at our centre, and what each patient needs to know before making a treatment decision.
Why Myopia Cannot Be ‘Cured’ the Way an Infection Can
To understand whether short-sightedness can be permanently cured, you first need to understand what causes it at a structural level. Nearsightedness occurs when the eyeball grows slightly too long, sometimes by less than 1 mm causing light to focus in front of the retina rather than directly on it. This is a permanent physical change in the anatomy of the eye.
Unlike an eye infection, which is caused by bacteria or viruses and can be eliminated with medication, this condition stems from the shape and length of the eye itself. No medication, eye drop, dietary supplement, or exercise can reverse this structural elongation. The eyeball does not shrink back to a shorter length regardless of what treatments are applied.
However and this is the critical distinction, while the underlying elongation cannot be reversed, the blurry vision it causes can be permanently corrected by surgically reshaping the cornea to compensate for the excess eye length. This is the foundation of modern laser refractive surgery, and it is the closest thing to a permanent cure available today.
Does Short-Sightedness Ever Get Better on Its Own?
No. Nearsightedness does not improve or reverse naturally under any circumstances. Once the eye has elongated, that length is permanent. However, in many adults typically between the mid-20s and early 30s the spectacle power does stabilise, meaning it stops increasing. This stabilisation is not a cure; the existing refractive error remains fully present. However, this stable period is clinically important because it is a mandatory prerequisite for laser surgery at MediVision Kukatpally. Our surgeons require at least 12 consecutive months of stable power before performing any refractive procedure.
| 🚫 4 Widespread Myths — Debunked by MediVision Doctors, KPHB:MYTH 1: Eye exercises reduce spectacle power. — FALSE. No peer-reviewed study has ever shown that exercises reduce the length of the eye or the spectacle number. MYTH 2: Removing glasses strengthens the eyes. — FALSE. Under-correction of nearsightedness in children may actually accelerate progression. MYTH 3: Eating carrots or special foods can cure the condition. — FALSE. Diet supports overall eye health but cannot alter the shape of the eyeball. MYTH 4: The eyes automatically improve after a certain age. — FALSE. Power stabilises in adulthood but never reverses. |
Surgical Options That Permanently Correct Nearsightedness
At MediVision Eye Care Centre, KPHB Colony, Kukatpally, our dedicated refractive surgery team offers all leading surgical correction options. Each works by compensating for the eye’s excess length through permanent alteration of the cornea or by implanting a corrective lens. Here is a detailed comparison:
| Procedure | Mechanism | Best For | Corrects Up To |
| LASIK | Excimer laser reshapes corneal tissue beneath a flap | Adults, mild to high power, adequate corneas | -12D |
| SMILE | Femtosecond laser extracts a lenticule through 2 mm incision | Dry eyes, active lifestyles, thin corneas | -10D |
| SILK | Smooth lenticule extraction — latest generation SMILE | IT professionals, fastest recovery | -10D |
| ICL | Biocompatible lens implanted inside the eye — no corneal removal | Very high power, thin corneas | -18D |
LASIK — The World’s Most Performed Refractive Procedure
LASIK (Laser-Assisted In Situ Keratomileusis) is backed by over three decades of clinical evidence and is the most commonly performed vision correction procedure globally. An excimer laser creates a precise ablation profile on the cornea removing microscopic amounts of tissue to flatten its curvature so that light focuses accurately on the retina after surgery. At MediVision Kukatpally, LASIK is performed using blade-free, wavefront-guided technology for maximum precision.
• Eligibility: Adults 18+ with stable power for 12 months, adequate corneal thickness
• Procedure time: 10–15 minutes per eye
SMILE – Flapless Surgery for Greater Comfort
SMILE (Small Incision Lenticule Extraction) creates no corneal flap. A femtosecond laser forms a small disc of corneal tissue inside the stroma called a lenticule which is then removed through a 2–3 mm incision, permanently altering the corneal shape. Because no flap is created, the biomechanical integrity of the cornea is better preserved, and the risk of post-operative dry eye is significantly lower than with traditional LASIK.
SMILE is the preferred option for patients with pre-existing dry eye, those involved in contact sports, and defence or law enforcement personnel in Hyderabad where corneal stability is critical.
SILK™ — The Latest Generation at MediVision
SILK (Smooth Incision Lenticule Keratomileusis) is the most advanced evolution of lenticule-based refractive surgery. Compared to SMILE, SILK uses a refined incision technique that results in an even smoother corneal surface and faster visual recovery. At MediVision Eye Care, KPHB, SILK is particularly sought after by young working professionals in Hyderabad’s IT and finance sectors who need the fastest possible return to screen-based work.

ICL – The Gold Standard for Very High Spectacle Power
For patients with power typically above -8D, or those with corneas too thin for laser ablation, ICL (Implantable Collamer Lens) is the superior choice. A biocompatible Collamer-material lens is implanted through a small incision into the posterior chamber between the natural crystalline lens and the iris without removing any corneal tissue whatsoever. The ICL corrects nearsightedness from approximately -3D up to -18D and can be explanted or exchanged if required in future.
Unlike laser procedures which alter the cornea permanently, ICL is technically reversible, making it an excellent option for younger patients who may require cataract surgery in later life. Our refractive surgeons at MediVision KPHB perform a detailed pre-ICL evaluation covering anterior chamber depth, endothelial cell count, and corneal topography before confirming suitability.
Why Surgical Correction Still Does Not Eliminate All Risk
It is important that every patient at MediVision Kukatpally understands a critical distinction: laser surgery or ICL corrects the refractive error of nearsightedness the blurry vision but it does not reverse the underlying elongation of the eyeball. The structural risks associated with high nearsightedness, including retinal thinning, increased glaucoma susceptibility, and macular vulnerability, remain present after surgery because the eye’s physical length is unchanged.
This is why our ophthalmologists emphasise that annual dilated retinal examinations remain essential even after successful refractive surgery, particularly for patients whose original power was -6D or above.
Pre-Surgery Assessment — Knowing If You Are a Candidate
Not every patient qualifies for every procedure. At MediVision Eye Care, KPHB Colony, Kukatpally, every potential surgical candidate undergoes a comprehensive pre-operative evaluation that assesses:
- Age — minimum 18 years for LASIK and SMILE; ideally 21+ for greatest power stability
- Refractive stability — no significant change in the past 12 consecutive months
- Corneal thickness — sufficient residual stroma must remain after ablation
- Corneal topography — to exclude irregular conditions such as keratoconus
- Tear film quality — to assess pre-existing dry eye and surgical suitability
- Intraocular pressure and retinal health — to exclude glaucoma or retinal disease
If a patient does not qualify for laser surgery, our surgeons discuss ICL or continued optical correction. No patient leaves MediVision Kukatpally without a clear understanding of all available options and the best path forward for their specific eyes.
Frequently Asked Questions
1: Can I stop wearing glasses completely after LASIK?
Yes, for most patients. The goal of LASIK is to eliminate dependence on glasses and contact lenses for distance vision. The vast majority of MediVision patients achieve 6/6 (20/20) vision or better and no longer need glasses for driving, sport, or work. Patients over 40 may still require reading glasses due to presbyopia — an age-related change in the natural lens that is entirely separate from nearsightedness.
2: How long does the correction from LASIK last?
The corneal reshaping performed during LASIK is permanent. It does not wear off or regress over time. In very rare cases — typically where surgery was performed on an unstable prescription — minor residual power may emerge years later. At MediVision Kukatpally, this can be addressed with an enhancement procedure at a significantly reduced cost.
3: My child is 15 with -5D. When can they have surgery?
Surgery is not performed before 18 years. The current priority is slowing progression through myopia control — low-dose atropine drops, Ortho-K lenses, or MiSight contact lenses. The aim is to stabilise the power as much as possible so that by age 18–21, your child is the best possible candidate for laser correction. Our paediatric team at MediVision KPHB will design a tailored plan.
4: Is LASIK safe for -9D myopia?
At -9D, suitability depends on corneal thickness and topography, which can only be assessed during the pre-operative evaluation. If corneal tissue is insufficient for safe ablation, ICL is the recommended alternative. ICL is highly effective at this power level and is routinely performed at MediVision Eye Care Centre, Kukatpally.
