Refractive Errors

The most common types of Refractive Errors are:

• Nearsightedness (also called myopia) is a condition where objects up close appear clearly, while objects far away appear blurry. Light focuses ahead of the retina in nearsightedness.
• Farsightedness (also called hyperopia) is a common type of refractive error where distant objects may be seen more clearly than objects that are near. Farsightedness affects people differently. Young people may not detect visual impairments. For people with significant farsightedness, vision can be blurry for objects at any distance, near or far.
• Astigmatism is a condition in which the eye does not focus light evenly onto the retina, the light sensitive tissue at the back of the eye. This can blur and stretch visuals.
• Presbyopia is an age-related condition in which the ability to focus up close becomes more difficult. As the eye ages, the lens can no longer change shape enough to allow the eye to focus close objects clearly. Presbyopia is common in individuals over the age of 40.

Blurred vision is the most common symptom. Refractive errors can generate different symptoms according on their nature and severity. Refractive error symptoms include:

• Blurred vision: It can cause blurred vision. Both near and far, objects may appear blurry.
• Myopia: Myopia causes trouble seeing distant objects. Myopia symptoms include squinting to focus, difficulty reading road signs or chalkboards, and a preference for sitting closer to the TV or movie screen.
• Hyperopia: Hyperopia can make reading and computer work difficult. Near tasks can cause eyestrain, headaches, and weariness in hyperopes.
• Distorted or Ghosting Vision (Astigmatism): Astigmatism causes distorted or uneven pictures. Double vision, ghosting, and wavy lines may occur.
• Eye Strain and Fatigue: This eye error can cause eye strain and fatigue, especially when reading, writing, or using digital gadgets.
• Squinting: Squinting naturally improves focus and clarity. Refractive defects can cause squinting.
• Headaches: Uncorrected refractive defects can cause headaches, especially following visual tasks.
• Eye Irritation: Uncorrected refractive defects can cause eye pain, dryness, or redness when the eyes strain to focus.
• Sensitivity to Light: Refractive errors may improve light sensitivity.

There are certain conditions for the suitability for the method of correction of this eye problem. The most common methods used to correct this error are:

• Glasses: Eyeglasses correct refractive problems. They have prescription lenses to correct the refractive defect. Single-vision lenses for nearsightedness, farsightedness, and astigmatism and bifocals or progressive lenses for presbyopia are available. Glasses fix refractive problems and improve vision without surgery.
• Contact Lenses: People who don't use glasses prefer contact lenses. Thin, curved lenses sit directly on the eye. Light-bending contact lenses cure refractive problems. They correct myopia, hyperopia, astigmatism, and presbyopia. Proper cleaning and management of contact lenses prevent eye infections and optimise vision correction.
• Refractive surgery: It corrects refractive problems permanently. LASIK, PRK, and SMILE are refractive operations. These techniques reshape the cornea to improve focusing, correcting refractive problems. Refractive surgery may eliminate the need for glasses or contacts. However, a comprehensive evaluation and consultation with a competent eye surgeon are necessary to establish operation suitability and risks and benefits.
• Orthokeratology: Ortho-K is a non-surgical refractive error treatment. Overnight gas-permeable contact lenses gently remodel the cornea. The lenses are removed in the morning, and the cornea remains its temporary shape for clear vision throughout the day. Ortho-K can temporarily remove myopia sufferers from glasses or contacts. To monitor corneal changes and optimise results, eye care professionals must follow up often.
• Phakic intraocular lenses (IOLs): These are another surgical alternative for refractive defect correction. These lenses go within the eye in before or behind the native lens. High myopia or hyperopia may require phakic IOLs. Implantable lenses correct refractive problems permanently and improve vision.

The kind and severity of the refractive problem, personal preferences, lifestyle variables, and eye health all affect treatment decision. Consult an optometrist or ophthalmologist for a thorough eye exam and treatment options at Save Sight Centre, Adarsh Nagar now. The eye doctor will assess your needs and recommend refractive correction and visual acuity improvements.

Know More About Contact Lenses

Vision correction surgery, commonly known as refractive surgery, corrects common refractive problems such myopia, hyperopia, and astigmatism. Refractive eye surgery reduces or eliminates the need for glasses or contacts.

Know More About Refractive Surgery

Refractive error stability, eye health, age, corneal thickness, lifestyle, and expectations determine surgery eligibility. An ophthalmologist or refractive surgeon must perform a thorough evaluation to establish eligibility. Also, which method will suit the most, is dependent on those examinations.

• LASIK: One of the most popular refractive eye operations is LASIK. It corrects refractive errors by producing a thin corneal flap and reshaping the corneal tissue using a laser.
• PRK (Photorefractive Keratectomy): Another laser-based surgery that reshapes the cornea without a flap. Instead, the epithelium is gently removed and the laser is delivered to the exposed cornea to rectify the refractive defect. Epithelium regenerates naturally.
• SMILE (Small Incision Lenticule Extraction): A revolutionary laser eyesight correcting method. It includes making a small incision and using a laser to remove a lenticule from the cornea, reshaping it and correcting the refractive defect.
• LASEK: LASIK and PRK are combined in LASEK. To expose the cornea, a thin epithelial flap is raised. Laser reshaping the cornea before flap repositioning.
• ICL (Implantable Collamer Lens): Refractive faults can be corrected by surgically implanting a special lens. The operation may put these lenses in before or behind the eye's natural lens. The collamer-based ICL corrects myopia, hyperopia, and astigmatism.
