Refractive errors are common vision problems that occur when the eye cannot properly focus light on the retina, the light-sensitive layer at the back of the eye. The eye works much like a camera — light enters through the cornea and lens, and the retina sends visual signals to the brain.
When the shape of the eye prevents light from focusing correctly on the retina, vision becomes blurred. Refractive errors are among the most common eye conditions and can usually be corrected with glasses, contact lenses, or refractive surgery.
At Sushila Hospital, we provide comprehensive diagnosis and advanced treatment options for refractive vision problems.
Myopia is a condition where distant objects appear blurry while nearby objects are seen clearly. It commonly develops during school or teenage years and may increase during periods of rapid growth.
People with high myopia should undergo regular eye examinations, as severe myopia may increase the risk of other eye conditions.
Hyperopia occurs when near objects appear blurred, while distant objects may appear clearer. It happens when light focuses behind the retina instead of directly on it.
Astigmatism occurs when the cornea has an irregular shape, causing light to focus unevenly on the retina. This results in blurred or distorted vision at both near and far distances.
Glasses are the safest and simplest method to correct refractive errors. Modern high-index lenses are thinner and lighter, providing comfortable and clear vision.
Contact lenses provide a convenient alternative to glasses. They sit directly on the eye and offer a wider field of vision. Proper hygiene and regular care are important to avoid infections.
LASIK (Laser-Assisted In-Situ Keratomileusis) is a modern laser vision correction procedure used to treat myopia, hyperopia, and astigmatism.
During LASIK, a highly precise laser reshapes the cornea so that light focuses properly on the retina, improving vision.
Benefits of LASIK include:
Candidates for LASIK should generally be 18 years or older and have a stable spectacle power for at least one year.
LASIK may be suitable for people who:
A detailed eye examination is necessary to determine whether LASIK is the right option.
LASIK is usually performed as an outpatient procedure, meaning patients can return home the same day.
The procedure typically takes only a few minutes per eye and is performed under local anesthetic eye drops, making it painless.
Most patients notice improved vision within a few days, with full stabilization occurring over the following weeks.
LASIK is a safe and widely performed procedure, but some patients may temporarily experience:
A comprehensive pre-surgery evaluation helps reduce these risks and ensures the best possible outcome.
If LASIK is not suitable due to factors like thin cornea or high refractive power, other treatments may be recommended, such as:
Our specialists at Sushila Hospital carefully evaluate each patient and recommend the most appropriate treatment.
Modern refractive procedures have helped millions of people achieve clearer vision and reduce their dependence on glasses.
At Sushila Hospital, our eye specialists use advanced technology and personalized treatment plans to help you achieve the best possible vision.
