CONTENTS

Did you know that cataract surgery is one of the most common surgical procedures performed worldwide? However, a common concern that arises post-surgery is the impairment of near vision after cataract surgery. If you’re struggling with this issue, you’re not alone.

This article will delve into why this happens and, most importantly, how to improve your near vision after cataract surgery. We’ll explore various solutions, from reading glasses to monovision LASIK, providing you with the information you need to regain clear, close-up vision. We will also explore ways to prevent this from happening all together.

The good news is that there are several ways to improve your near vision after cataract surgery. Here are some of the most effective solutions:

  • Reading Glasses: These are a simple and cost-effective solution. They can be easily adjusted to your needs and are particularly useful for tasks like reading or using a computer. Over the counter reading glasses can be tried. Sometimes prescription reading glasses are necessary if over the counter readers are not working well.
  • Progressive Glasses: These glasses have a gradient of power that allows you to see clearly at different distances. The top part of the lens is for distance vision, the middle part for intermediate vision, and the bottom part for near vision.
  • Monovision Contact Lenses: With this approach, one eye is corrected for distance vision, and the other eye is corrected for near vision. Your brain learns to prioritize the eye that provides the clearest image for the task at hand. If you have no tried monovision before, then monovision can take some getting used to. Some patients ultimately are not able to adapt.
  • Monovision LASIK: Similar to monovision contact lenses, this surgical procedure corrects one eye, the non-dominant eye for near vision. It’s a more permanent solution than glasses or contacts. If you have never tried monovision before then it will be important to do a trial with monovision contacts first.

Monovision Options to Improve Near Vision After Cataract Surgery

Monovision is a strategy often used to help people who have difficulty seeing both near and far objects clearly, a condition known as presbyopia. This approach involves correcting one eye for distance vision and the other for near vision. Here are the two main monovision options available after cataract surgery:

  • Monovision Contact Lenses: This is a non-surgical option where you wear a contact lens in one eye to correct your distance vision and a different contact lens in the other eye to correct your near vision. This allows you to see clearly at all distances. Your brain learns to prioritize the eye that provides the clearest image for the task at hand, whether it’s reading a book or looking at a distant object. It’s worth noting that it can take some time to adjust to monovision contact lenses, and not everyone finds them comfortable or effective.
  • Monovision LASIK: This is a surgical option where LASIK (Laser-Assisted In Situ Keratomileusis) surgery is used to correct one eye for distance and the other for near vision. This is a more permanent solution than glasses or contacts. During the procedure, a laser is used to reshape the cornea, which helps to focus light that enters the eye, improving vision. Monovision LASIK has the advantage of being a one-time procedure with no need for glasses or contact lenses. However, as with any surgical procedure, there are risks involved, and it’s important to discuss these with your eye doctor.

It’s important to note that monovision isn’t suitable for everyone. Some people may find it difficult to adjust to having each eye corrected for a different purpose. It can also affect depth perception, which could be problematic for people who regularly participate in activities where this is important, such as sports. If you’re considering monovision, it’s often recommended to trial it with contact lenses first to see if it’s a good fit for you.

Why Near Vision Can Be Impaired After Cataract Surgery

The impairment of near vision after cataract surgery can be attributed to several factors:

  • Type of Intraocular Lens (IOL) Used: During cataract surgery, the natural lens of the eye, which has become clouded due to the cataract, is replaced with an artificial lens known as an intraocular lens (IOL). There are different types of IOLs available, and the type used can impact your vision after surgery. For instance, a monofocal IOL is designed to provide clear vision at one distance (near, intermediate, or far), but not all distances. If a monofocal IOL set for distance vision is used, you may find your near vision is not as clear after surgery.
  • Adjustment Period: After cataract surgery, your brain needs to adjust to the new way of seeing. The signals your eyes send to your brain change after your natural lens is replaced with an artificial one. This can cause blurry vision, including near vision, immediately after surgery as your brain learns to interpret these new signals.
  • Residual Refractive Error: Sometimes, despite the precise calculations done before surgery, the power of the IOL may not perfectly correct the eye’s refractive error, and some degree of nearsightedness, farsightedness, or astigmatism may remain. This can affect the clarity of your near vision.
  • Post-Surgery Complications: Although rare, complications after cataract surgery like swelling, infection, or issues with the position of the IOL can affect your vision, including near vision.
  • Pre-existing Eye Conditions: If you have a pre-existing eye condition like macular degeneration, glaucoma, or diabetic retinopathy, it could affect your vision after cataract surgery, including your near vision.

Preventing Loss of Near Vision with Cataract Surgery

Preventing the loss of near vision after cataract surgery is largely dependent on the choices made before the procedure, particularly the type of intraocular lens (IOL) implant selected and the decision to opt for monovision cataract surgery. Here’s a closer look at these two factors:

Selecting the Right Lens Implant

The type of IOL used in cataract surgery can significantly impact your near vision post-surgery. Here are the main types of IOLs:

  • Monofocal IOLs: These are the most commonly used IOLs. They have one point of focus and can be set to correct for distance, intermediate, or near vision. However, they cannot correct for all ranges at once. If a monofocal IOL is set for distance vision, you may need reading glasses for near tasks after surgery.
  • Multifocal IOLs: These lenses have multiple points of focus and can correct vision at multiple distances. They can provide good near and distance vision, reducing the need for glasses after surgery. However, some people may experience halos or glare around lights with these lenses.
  • Extended Depth of Focus (EDOF) IOL: EDOF lenses are designed to provide a continuous range of high-quality vision for far, intermediate, and near distances, with less incidence of halos and glare. They work by extending the focus of the eye, providing a smoother transition between different distances compared to multifocal lenses.

Monovision Cataract Surgery

Monovision cataract surgery is another option to prevent the loss of near vision. This approach involves implanting an IOL set for distance vision in one eye and an IOL set for near vision in the other eye. This allows one eye to see clearly at a distance and the other to see clearly up close, reducing or eliminating the need for glasses.

Your brain learns to prioritize the eye that provides the clearest image for the task at hand, whether it’s reading a book or looking at a distant object. It’s worth noting that it can take some time to adjust to monovision, and not everyone finds it comfortable or effective.

Choosing a multifocal or EDOF IOL or the decision to opt for monovision cataract surgery can play a significant role in preventing the loss of near vision after cataract surgery. Its important to know your best lens options BEFORE cataract surgery. Discuss these options with your eye doctor to determine the best solution for your specific needs and lifestyle.

Potential Causes of Ongoing Blurred Vision After Cataract Surgery

If your near vision remains blurry for an extended period after cataract surgery, it could be due to several reasons:

  • Inflammation: Post-operative inflammation is a common occurrence that can cause temporary blurriness.
  • Dry Eyes: Dry eyes can affect the quality of your vision. Your doctor may recommend using artificial tears to alleviate this issue.
  • Posterior Capsular Opacification (PCO): PCO is a condition where a cloudy layer of scar tissue forms behind the IOL, causing blurred vision. This can be treated with a quick laser procedure known as YAG laser capsulotomy.
  • Retinal Detachment or Cystoid Macular Edema: These are more serious conditions that can cause blurred vision.

Conclusion

Improving your near vision after cataract surgery is a process that requires patience and proper care. Whether you choose a non-surgical solution like glasses or contacts, or opt for a surgical procedure like monovision LASIK, the goal is to enhance your quality of life by improving your vision. Always consult with your eye doctor to discuss the best options for your specific needs and lifestyle. Remember, each person’s journey to clear vision is unique, and what works best for one person may not be the best solution for another.
