Most patients experience significantly improved vision after the full recovery period from cataract surgery, but some do still require glasses to achieve their best vision. This depends mainly on the lens chosen by the patient for implantation.
One of the most important aspects of your cataract surgery will be choosing your new intraocular lens (IOL.) In order to choose the ideal IOL for your vision and lifestyle needs, we at Isha Netralaya make sure all of our patients are fully aware of their treatment options, as well as the details of those options.
Monofocal IOLs are designed to create a patient’s clearest possible vision at one distance. The distance chosen can be near, intermediate, or far. Most of our patients who choose monofocal IOLs go with far-distance focusing and then occasionally wear reading or magnifying glasses when the need arises. We, at Isha Netralaya, provide the wide range of most advanced monofocal IOLs available.
Traditional intraocular lenses have a spherical optical design, meaning the front surface is uniformly curved from the center of the lens to its periphery. This design does not mimic the shape of the natural lens inside the eye, which varies in curvature from center to periphery. In other words, the eye’s natural lens is aspheric (“not spherical”).
A spherical intraocular lens can induce minor optical imperfections called higher-order aberrations (HOAs), which can affect quality of vision, particularly in low-light conditions such as driving at night.
Premium aspheric IOLs, on the other hand, match more closely the shape and optical quality of the eye’s natural lens, and thereby can provide sharper vision — especially in low light conditions and for people with large pupil size.
Toric IOLs are premium intraocular lenses that correct astigmatism (cylindrical power) as well as nearsightedness or farsightedness.
Toric IOLs can correct astigmatism (Cylindrical power) because they have different powers in different meridians of the lens. They also have alignment markings on the peripheral part of the lens that enable the surgeon to adjust the orientation of the IOL inside the eye for optimal astigmatism correction.
Toric IOLs decrease the likelihood of needing additional surgical procedures to reduce residual astigmatism
Multifocal IOL (Bifocal and Trifocal lenses):
Multifocal IOLs are a category of presbyopia-correcting IOLs that can decrease your need for reading glasses or computer glasses after cataract surgery.
Like multifocal contact lenses or progressive glasses, these premium IOLs contain added magnification in different parts of the lens to expand your range of vision so you can see objects clearly at all distances without glasses or contact lenses.
Your cataract surgeon can help you decide if you are a good candidate for multifocal IOLs at your preoperative exam and consultation. Laser cataract surgery often is recommended if you are a good candidate for multifocal IOLs, because precise alignment of these lenses is very important to give you the best visual outcome at all distances.
Traditional multifocal lenses have two foci,i.e. Bifocalwhich work for far distance and either intermediate or near distance. So effectively the spectacle independence with traditional bifocal IOLs is partial.
Newer generation multifocal IOLs, due to its’ innovative technologies, have provided the patients with option to go for complete spectacle free post cataract surgery vision. These are effectively trifocal lenses which provide patients with good near, intermediate and distance vision.
At Isha Netralaya, our doctors and counsellors are dedicated to inform patients about all the options available for intraocular lenses as per patient’s requirements and lifestyle.
We do recommend Trifocal lenses for all eligible candidates to achieve the optimal spectacle free vision at near, intermediate and far distance.
PANOPTIX® TRIFOCAL LENSES:
As the one and only trifocal lens implant approved by the US FDA, the AcrySof IQ PanOptix® trifocal IOL is an exciting new option for cataract patients. This remarkable new lens is able to provide corrected near, intermediate, and distance vision. As a result, the PanOptix® trifocal lens can significantly decrease patients’ reliance on glasses following cataract surgery compared to other IOL types.
The PanOptix® trifocal lens, which incorporates ENLIGHTEN® Optical Technology, can provide patient’s best possible intermediate vision without negatively affecting near and distance vision. Further, this unique lens technology is also available in the PanOptix® toric lens, meaning certain patients with astigmatism could also be eligible candidates.
