A cataract is the clouding of the eye’s natural lens, which normally helps focus light. During cataract surgery, this cloudy lens is removed. Because the eye still needs focusing power after the procedure, the natural lens must be replaced with an artificial intraocular lens (IOL). This replacement lens allows patients to regain clear vision and, in many cases, significantly reduce their dependence on glasses after surgery.

Yes. Just as there are major differences between car brands or clothing brands, there are also important differences between artificial lenses used in eye surgery. There are many different types and quality levels of intraocular lenses available. The choice of lens has a significant impact on your vision after surgery.

Premed Pharma is committed to making high-quality, state-of-the-art intraocular lenses available for ophthalmic surgery, including the FineVision^® premium lens families designed to provide excellent visual outcomes.

Traditional monofocal lenses provide excellent sharp vision at one selected distance only. Most patients choose clear distance vision without glasses, but in this case glasses are still usually needed for activities such as reading, computer work, or other close-up tasks.

Multifocal lenses — including FineVision^® trifocal lenses — provide sharp vision across a much wider range of distances. They help patients maintain a more active, glasses-independent lifestyle. With these lenses, patients can generally see distant objects clearly while also seeing objects at arm’s length. Everyday activities such as using a computer, reading a mobile phone screen, recognizing faces, reading, or watching television become much easier without glasses. Because of these advantages, more and more patients choose multifocal lenses to reduce their need for spectacles.

Trifocal lenses are designed to provide good visual acuity at near, intermediate, and far distances.
During the first few weeks after surgery, patients gradually adapt to their “new vision.” After approximately 1–2 months, the visual experience usually becomes completely natural.

Trifocal lenses can restore vision that is close to the clarity many people experienced when they were younger. These FineVision^® lenses are designed to provide sharp vision at all distances while greatly reducing or eliminating the need for glasses.

Yes. Like any surgical procedure, cataract surgery carries some degree of risk. However, the risk is very low. Unexpected complications occur in approximately 0.5% of cases — about 1 complication in every 200 surgeries. Any symptoms that appear after surgery should be examined promptly, as early evaluation allows potential problems to be identified and treated in time.

Depth perception depends on both eyes working together. If monofocal lenses were used so that one eye focused only for distance and the other only for near vision, the patient’s depth perception could be significantly impaired.
This could become dangerous in certain situations, such as driving or walking on uneven ground.
Thanks to FineVision^® trifocal technology, modern FineVision^® intraocular lenses can provide clear vision at all distances after surgery, allowing patients to see well both near and far while maintaining normal binocular vision.

After surgery, the eye may remain sensitive for a few days, which is completely normal. Full healing takes several weeks. During recovery, patients may experience mild stinging sensations, slight foreign-body sensation, or minor eye discharge. Some people may temporarily notice floating shadows or altered color perception.
In most cases, however, vision becomes more comfortable day by day, symptoms gradually improve, and eyesight steadily sharpens.

During the weeks after surgery, patients gradually learn to fully use their new vision. After 1–2 months, most people describe the experience as comfortable, natural, and “as if it had always been this way.”

Not exactly. With multifocal glasses, the different prescription zones are positioned in separate parts of the lens, so the wearer must tilt their head and move their eyes to find the correct focus area. A multifocal intraocular lens, however, is placed inside the eye and moves naturally together with the eye itself. Because of this, no special head movements are required. As a result, adaptation is usually easier and smoother, and the visual experience feels more natural.

The vast majority of patients adapt to FineVision^® trifocal lenses without any significant difficulty. In extremely rare cases, however, some patients may not be able to adapt successfully. In such situations, it is theoretically possible to replace the trifocal lens with a monofocal lens during another surgical procedure.
