Lasik Presbyopia - PresbyLasik
Do you have difficulty reading up close and have to hold your glasses at arm's length? Presbyopia is a natural aging disorder that affects everyone after 40-45 years. PresbyLasik in Tunisia is a surgical technique that corrects near vision and reduces your dependence on reading glasses. In Tunisia, experienced ophthalmologists perform this procedure at competitive prices.
What is presbyopia?
Presbyopia is a natural and inevitable visual disorder related to the aging of the crystalline lens. It generally appears around 40-45 years and manifests as increasing difficulty seeing up close. The lens, which ensures focusing, progressively loses its flexibility with age, making near vision increasingly blurry. Presbyopia affects 100% of the population and generally requires wearing reading glasses or progressive lenses.
How does PresbyLasik work?
PresbyLasik in Tunisia is a surgical technique that uses the excimer laser to reshape the cornea and create a near vision zone in the center of the cornea, while preserving distance vision in the periphery. This technique is inspired by the monovision principle: one eye is corrected for near vision, the other for distance vision. The brain fuses the two images naturally to provide comfortable vision at all distances. PresbyLasik is customized according to each patient's visual needs.
Available techniques
Several techniques are available to correct presbyopia. PresbyLasik uses the excimer laser to create a near vision zone. FemtoPresbyLasik combines the femtosecond laser with the excimer laser. IntraCor uses the femtosecond laser to create circular incisions in the cornea. This technique modifies the curvature without creating a flap. Multifocal or accommodative implants are an alternative in case of associated cataract.
Ideal candidates
PresbyLasik is intended for patients aged 40 to 65. It treats troublesome presbyopia in daily life. Candidates must be in good ocular health. They must not have major pathologies such as cataract or glaucoma. The cornea must be sufficiently thick. A complete preoperative assessment determines eligibility. PresbyLasik can correct associated myopia, hyperopia or astigmatism.
The preoperative assessment
Before PresbyLasik, a complete ophthalmological assessment is performed. It measures near and distance visual acuity. The slit lamp checks the lens and cornea. Corneal topography analyzes the shape and thickness. Pachymetry, aberrometry and intraocular pressure are measured. A simulated monovision test is also performed. It assesses your tolerance to differential correction of the two eyes.
The procedure
The PresbyLasik procedure is quick and painless. It is performed under local anesthesia with drops. The patient lies under the laser. Eyelid holders prevent blinking. The corneal flap is created for PresbyLasik. Intrastromal incisions are made for IntraCor. The laser is activated to reshape the cornea. The patient fixates on a blinking red light. The procedure lasts 15 to 30 minutes for both eyes. The patient goes home within the following hour.
Recovery after PresbyLasik
Recovery after PresbyLasik is quick. Clear vision is generally restored within 24 to 48 hours. Temporary discomfort may be felt, such as tearing or a foreign body sensation. Local treatment with eye drops is prescribed. Adaptation to the new vision may take a few weeks. The brain gets used to the differential correction of the two eyes. Return to work is possible the next day.
Presbyopia and other visual defects
Presbyopia is often associated with other visual defects. PresbyLasik can correct presbyopia and these defects simultaneously. The strategy is personalized according to the visual profile, age and daily needs. Monovision is particularly suitable for myopic patients. Hyperopic patients often obtain excellent results with PresbyLasik.
What is the price of PresbyLasik in Tunisia?
Tunisia offers very competitive prices for presbyopia surgery. PresbyLasik costs between €1,800 and €2,500 for both eyes. FemtoPresbyLasik is priced from €2,200 to €3,000. IntraCor by femtosecond laser ranges from €2,500 to €3,500. A complete package includes assessment, procedure and follow-up. These prices are up to 50% cheaper than in Europe, without compromising on quality.
Frequently Asked Questions about PresbyLasik
1Can presbyopia surgery be performed at the same time as cataract surgery?
Yes, presbyopia correction can be performed simultaneously during cataract surgery. In this case, the surgeon implants a multifocal or accommodative intraocular lens that corrects both cataract and presbyopia. This approach treats both problems in a single procedure and provides clear vision at all distances without glasses.
2How long does it take to adapt to monovision after PresbyLasik?
Adaptation to monovision is a progressive process that varies among patients. Most people adapt in 2 to 4 weeks, but some may need up to 3 months. During this period, the brain learns to fuse the images from both eyes to provide clear vision at all distances. A simulated monovision test is performed before the procedure to assess your adaptation capacity.
3Is PresbyLasik reversible in case of poor adaptation?
PresbyLasik is not reversible in the sense that the cornea is permanently reshaped. However, in case of poor adaptation to monovision, it is possible to perform a laser touch-up to adjust the correction. In some cases, wearing light reading glasses can also compensate. Preoperative simulation minimizes the risk of poor adaptation.
4What is the difference between a multifocal implant and PresbyLasik?
PresbyLasik acts on the cornea by reshaping it to create a near vision zone, while the multifocal implant replaces the natural lens with an artificial lens that allows seeing at multiple distances. The multifocal implant is generally recommended in case of cataract or for patients over 55. PresbyLasik is more suitable for patients aged 40 to 55 without cataract.
5Can presbyopia continue to progress after PresbyLasik?
Yes, presbyopia continues to progress with age, even after PresbyLasik. The lens continues to age and lose its flexibility. However, the procedure provides a lasting correction that significantly reduces dependence on reading glasses for 5 to 10 years. After this period, a touch-up may be considered or wearing light reading glasses may become necessary.
6Can PresbyLasik be performed on both eyes at the same time?
Yes, PresbyLasik is generally performed on both eyes on the same day in most clinics. This simultaneous bilateral approach has several advantages: reduced stress related to two separate procedures, fewer travel requirements and no optical discrepancy between the two eyes. Each eye receives an adapted correction (one eye for distance vision, the other for near vision).
7What is the quality of night vision after PresbyLasik?
After PresbyLasik, some patients may experience night discomfort with halos or glare around light sources, particularly during the first weeks. These effects are generally temporary and gradually decrease as the brain adapts. Modern technologies of customized laser and aberrometry significantly reduce these side effects.
