Presbyopia
3min ReadTreatment of presbyopia with surgical methods on the cornea
Presbyopia is defined as: the gradual loss of elasticity of the lens and the reduction of the eye’s ability to adapt. These two factors are inseparable from the natural aging process. Almost all people have presbyopia when they reach the age of 40 or 50, and as a result, the ability to focus on close objects is reduced and it affects tasks such as reading, sewing or working with a computer. Lays. The traditional approach to treating presbyopia involved the use of reading glasses or multifocal lenses. However, surgical interventions on the cornea have revolutionized the treatment landscape.
Common symptoms of presbyopia:
- Difficulty in reading fine print
- Difficulty seeing at night
- Dry eyes
- Combination of objects in the background
- Red and swollen eyelids
- Presence of floating spots or spots in the vision
- Flashes of light
- Sensitivity to light
- Cataract
- Age-related macular degeneration (AMD)
- Diabetic retinopathy
- Ocular melanoma
- Sleep disorder
Corneal surgery methods:
- Monovision technique: The monovision technique involves correcting one eye for distance vision and the other for near vision. It uses the brain’s ability to interpret visual information from both eyes and provides a practical solution for presbyopia. Although it may take time to adjust the brain, many people achieve satisfactory results with this method.
- Corneal Inlay: Another promising surgical procedure is the placement of a corneal inlay. These tiny implanted devices are placed inside the cornea and reshape it, improving near vision without compromising distance vision. Inlays such as Kamera or Presbia Flexivue microlenses have shown positive results in clinical trials and restore clear vision for presbyopic people.
- Multifocal LASIK or PRK: Using laser technology, multifocal LASIK or PRK (photorefractive keratectomy) procedures correct the cornea to create specific focal points for near, medium and far vision. This method allows patients to enjoy clearer vision in all ranges without the need for glasses or contact lenses.
- Lens implantation: In this method, ophthalmologists remove the lens of each eye and replace it with an artificial lens. This lens is called an intraocular lens. There are several types of lens implants available to correct presbyopia. Some allow your eyes to see objects both up close and far away. Some change position or shape inside the eye (accommodating lens). But lens implants can reduce the quality of your near vision, and you may still need reading glasses.
Advantages and considerations:
1- Reducing dependence on corrective lenses: One of the primary advantages of corneal surgery methods is reducing or eliminating the need for reading glasses or bifocals, increasing comfort and independence.
2- Convenience and immediate results: Corneal surgeries for presbyopia often provide quick results. and patients experience better vision on the same day or within a few days after the operation. This aspect makes it an attractive option for those seeking immediate visual improvement.
3- Individual Suitability: Successful results may vary based on individual factors such as eye health, corneal thickness, and overall vision. A thorough preoperative examination and consultation with a qualified eye care professional is essential to determine the most appropriate surgical option for each patient.
Potential risks and limitations:
While corneal surgery procedures for presbyopia have generated enthusiasm, as with any surgical procedure, there may be temporary visual disturbances during the recovery process. These are usually transient and resolve over time. Results can vary between individuals and the level of satisfaction may depend on personal expectations and compatibility with the chosen surgical procedure.
Conclusion:
Corneal surgery methods have provided a new way to treat presbyopia and offer alternatives to traditional corrective lenses. Techniques such as monovision, corneal inlays, and multifocal LASIK or PRK have shown promising results in restoring clear vision at various distances. However, it is important to remember that individual fit and careful evaluation by an experienced eye care professional are critical in determining the most appropriate surgical procedure for each patient.
