Farsightedness

Diagnosis

Farsightedness can be detected through a comprehensive and painless eye examination conducted by either an optometrist or an ophthalmologist. In this examination, special eye drops are used to enlarge the pupils, allowing more light to enter the eyes and providing a clearer view of the deeper parts, such as the retina. During this process, the healthcare provider utilizes various instruments and shines light into the eyes to assess overall eye health, not only identifying refractive errors like farsightedness but also screening for other conditions such as glaucoma and cataracts. If any symptoms related to vision impairment arise, it is advisable to promptly schedule an eye exam, as some farsightedness symptoms, like blurry vision, can indicate more serious underlying issues that require timely treatment.

Treatment

Corrective Lenses: Farsightedness can be managed through corrective lenses or refractive surgery. Young individuals may not always need treatment, as their flexible crystalline lenses can compensate. However, with age, prescription lenses may become necessary to enhance near vision. These lenses work by compensating for the flattened cornea curvature or shorter eye length associated with farsightedness. Prescription options include:

• Eyeglasses: A safe and straightforward option with various types like single vision, bifocals, trifocals, and progressive multifocals.
• Contact lenses: Worn directly on the eyes, these come in diverse materials and designs, including soft, rigid, gas permeable, and multifocal options. Consult your eye doctor for the most suitable choice.

Refractive surgery: Refractive surgery procedures, typically used for nearsightedness, can also address mild to moderate farsightedness by reshaping the cornea’s curvature. These methods include:

• LASIK (Laser-assisted in situ keratomileusis): A surgeon creates a thin corneal flap, then uses a laser to adjust the cornea’s shape, correcting farsightedness. LASIK offers quicker recovery and less discomfort compared to other corneal surgeries.
• LASEK (Laser-assisted subepithelial keratectomy): An ultra-thin flap is made in the outer corneal layer (epithelium), and a laser reshapes the cornea before replacing the epithelium.
• PRK (Photorefractive keratectomy): Similar to LASEK but with complete removal of the epithelium, followed by corneal reshaping. The epithelium regrows naturally to match the new corneal shape.

It’s crucial to discuss potential side effects of refractive surgery with your doctor before making a decision.
