Toric Lens Implants
A toric intraocular lens treats both cataracts and astigmatism with one procedure. Typically, patients who undergo cataract surgery receive a monofocal intraocular lens (IOL) that does not correct pre-existing vision problems, such as corneal astigmatism. If a patient has astigmatism, astigmatism must also be corrected, which can be achieved with Toric Lens Implants in Encino, CA.
A toric or astigmatism lens corrects preexisting astigmatism by refractive astigmatism reduction which is accomplished by an astigmatism correction in the IOL. During surgery, the IOL must be precisely positioned at the axis of astigmatism in the eye. This is accomplished by externally marking the eye prior to surgery and by using an intraoperative aberrometer to ensure precise implantation of the toric IOL.
What are the benefits of Toric Lens Implants?
The toric lens implants provide a better quality of uncorrected vision even with low to higher levels of astigmatism when compared to regular or spherical lens implants. A toric lens implant will bring the image into sharper focus on the retina even with the presence of mild residual astigmatism when compared to non-toric or regular implants.
Who would be a good candidate for toric lens implants in Encino, CA?
If you have astigmatism and prefer not to have to wear glasses for close up work such as reading or working on the computer, toric multifocal IOLs could be a great option for your cataract replacement lenses. These lenses may or may not return you to 20/20 vision, but they will likely deliver accurate enough vision that you will no longer need any eyeglasses for a broader range of activities.
How are toric IOLs implanted?
The process for placing toric IOLs with Dr. Aizuss is basically the same as any cataract surgery, but there are a couple important differences.
Prior to surgery, measurements are taken to enable Dr. Aizuss to choose the most beneficial toric IOL power and the required orientation of the implant in the eye to successfully correct the patient’s astigmatism.
Toric IOLs have special markers on the peripheral parts of the lens that enable Dr. Aizuss to see the orientation of the astigmatism correction in the lens. Once the toric IOL is implanted in the eye, he rotates the lens so the astigmatism correction is properly aligned and further confirms that placement with the advanced ORA system.
Does a toric lens procedure require anesthesia?
As mentioned above, these cataract procedures are the same whether having a toric lens or any other IOL placed. These procedures take just a few minutes. Dr. Aizuss first numbs your eyes with anesthetic eye drops. If you desire, we also can provide an intravenous sedative prior to your surgery so you’ll feel completely relaxed.
What to expect during recovery
You’ll wear an eye shield immediately after your surgery which you may remove when you put in your first set of eye drops about three hours after surgery. Dr. Aizuss will also have you wear the protective eye shield when sleeping, for 3 nights. At first your vision may be blurry, but it will rapidly improve within just a few days. Your eye may itch and be mildly uncomfortable, but you must not rub or place any pressure on it. Most patients eye comfort is close to normal by the morning after surgery.
Heavy lifting or exertion that creates pressure in the head area is advised against for three to five days. Eye drops will help with inflammation and infection, and they help control the pressure in the eye when needed.
You can resume daily activities by the day after surgery, but full healing can take up to six weeks. Surgery is done on only one eye at a time. If your other eye also needs surgery, we’ll schedule it for as soon as one week after this first surgery.
Are lens implants a permanent solution
All IOLs, including toric IOLs, are intended to last the remainder of the patient’s life. They will not degrade in any way. They will not cloud as your natural lens did as the proteins built up as the cataract developed. Unlike contact lenses, intraocular lenses never need replacing and they never require any cleaning or other maintenance. You’ll be happy with your astigmatism corrected vision for the rest of your life.
What are the risks of a lens implant procedure?
Cataract surgery is so common that eventually over half of the population will likely have it. Not only is the surgery commonplace, but it is the most successful surgery performed, with a success rate of 98 percent. Once the cataract-clouded natural lens is removed, it needs to be replaced with an IOL, whether toric or any other option. Complications are very rare, and if any of these happen, they can usually be successfully treated. These are the risks:
- Drooping eyelid
- Dislocation of the IOL
- Retinal detachment
- Loss of vision
This procedure in no way increases the very low risks involved with cataract surgery, but if the toric IOL is not placed in the proper alignment, it can cause blurred vision. This is a very rare possibility but would need to be corrected with another surgery. In our practice, we almost never need to reposition a toric lens as we confirm placement of the lens at the time of surgery with the advanced ORA system.
