Phakic intraocular lenses (phakic IOL)
Verisyse phakic intraocular lens IOL
Laser refractive corneal surgery (Pallikaris procedure, Intralase LASIK …) is sometimes not recommended for permanent diopter removal
Contraindications for laser refractive operations are:
- High myopia (usually more than -10.00 diopters)
- to thin cornea, irregular shape cornea
- Eye diseases and syndromes such as keratoconus or chronical eye dryness
For persons with some of the contraindications mentioned above, phakic intraocular lenses (phakic IOL) placement can be an ideal solution.
Phakic IOLs are transparent lenses that are surgically placed between the cornea and iris or immediately behind the iris, without removing the natural eye lens. This gives the patient a natural eye accommodation for short distances of viewing, with complete correction of visual acuity, since the phakic lenses allow proper focusing of the light on eye background and watching without glasses.
Installation of a phakic intraocular lens
Such lens is easily removed if it is necessary to replace, so the operation is reversible and is therefore ideal for patients who cannot correct the diopter in any other way.
In our polyclinic, we incorporate the modern lenses of the world’s best manufacturers (Verisyse, Veriflex and Visian ICL)
Verisyse is a phakic ocular lens that is placed in the ocular front cabin, in front of the iris. Used to correct myopia of -5.00 to -20.00 diopters.
Veriflex lens is a phakic IOL made of flexible material which allows even smaller cut during placement and thus better and faster recovery after surgery.
Top quality lens made of patented Collamer material, fully biocompatible.
Used for diopters:
- myopia from -1 to -20
- hyperopia from +1 to +10
- astigmatism up to 6 diopters
Advantages of Visian ICL lens:
- premium UV protection
- Does not cause dry eye syndrome
- The operation is reversible and can be combined with different operations in the future
- A great clinical experience – over 250,000 lenses implanted since 1997.
- Rapid postoperative recovery
- The lens is invisible in the eye and aesthetically ideal solution
The operation is brief, performed in local anesthesia with droplets and recovery is quick. Immediately after the operation it is not advisable to operate the motor vehicle. For only a few days, visual acuity achieves maximum values.
Application of multifocal lens in the eye – solution of diopter at all distances
What is an intraocular lens (IOL)?
Intraocular lens is a soft polymer implant – silicone or acrylic technologically trimmed to perfection that is embedded in the eye to improve vision.
Multifocal intraocular lens IOL
When it is embedded in the eye?
During the cataract surgery, the natural blurred lens is removed from the eye and the artificial intraocular lens is attached (AFACTIC LENS) which provides a clear distant vision.
For the successful implementation of the intraocular lens it is necessary to accurately measure the IOL strength before the so-called biometrics and consultation with the operator about the selection of the best lenses depending on the needs and wishes of the patient.
Types of intraocular lenses:
The traditional MONOFOCAL (single-strength) IOL focuses the beam of light in one point in the distance, which provides excellent distant vision.
TORIC MONOFOCAL IOL are a new generation of cylindrical intraocular lenses that, beside usual spherical diopter, can also correct astigmatism to achieve a higher quality of vision in patients with astigmatism.
MULTIFOCAL LENS is specially designed to create more focus at different points and to mimic natural accommodation, i.e. clear far and close vision, making the patient independent of the spectacles and contact lenses.
There are several types of multifocal intraocular lenses:
- REFRACTIVE intraocular lenses work on a similar principle as multifocal contact or eyeglasses (progressive) lenses, with three zones that simultaneously provide vision for proximity, mid-distance and distance.
- DIFFRACTIVE intraocular lenses represent the highest technological achievement among intraocular lenses due to good visual acuity in proximity and distance. The lenses can be BIFOCAL and TRIFOCAL, depending on how much visual acuity they provide after implantation.
Symfony intraocular lens IOL
- SYMFONY INTRAOCULAR LENS is the newest product of Abott Medical Optics with the so-called wide vision range. This technology has been able to minimize all the shortcomings of classical multifocal lenses, such as glittering, halo, harder adaptation, and a lesser contrast feeling.
