Why You Need A Lens Implant (IOL) With Cataract Surgery

Understanding Cataract Surgery

Cataract surgery is a surgical procedure that involves removing the clouded natural lens in your eye.  The clouded lens in your eye still has an “optical power” to help focus light.  You need a replacement lens known as a lens implant (IOL) to replace the “optical power” of your eye.  The lens implant (IOL) helps your eye focus. Your lens implant (IOL) serves as a permanent replacement of your eye’s natural, clouded lens.   

What Is an Intraocular Lens (IOL)?

An intraocular lens (IOL) is a small, biocompatible artificial lens that is implanted into the eye during cataract surgery. The lens implants are usually made from acrylic plastic, but some are silicon or Polymethylmethacrylate (PMMA) material.  IOLs come in various sizes and types.  Each IOL is designed to address specific vision needs. The most common types of IOLs include:

Monofocal IOLs: Monofocal IOLs are designed to provide clear vision at a specific distance, usually for distance vision. If you choose a monofocal IOL you may still need glasses for tasks such as reading or close-up work.

Multifocal IOLs: Multifocal IOLs are engineered to provide clear vision at multiple distances, typically for both near and far vision. If you choose a multifocal IOL, you often experience a reduced dependence on glasses for everyday activities.

Toric IOLs: Toric IOLs are specifically designed to correct astigmatism in addition to correcting your vision. They can significantly improve both distance and astigmatic vision.

Why a Lens Implant Helps:

Improved Vision Clarity:  Replacing your cataract-affected lens with an IOL, gives you the opportunity to restore clear vision.

Enhanced Quality of Life: Clear vision is essential for a high quality of life. Cataract surgery with the appropriate IOL can help you see the world with better clarity.  This can make your daily activities like reading, driving, and recognizing faces easier and more enjoyable.

Reduced Dependency on Glasses: Depending on the type of IOL you choose, you can experience a significant reduction your dependence on eyeglasses or contact lenses. Multifocal and toric IOLs can provide you with excellent vision at various distances, reducing or eliminating the need for corrective eyewear.

Customized Solutions: IOLs can be tailored to your specific visual needs.  We work closely with you to select the IOL that best matches your unique requirements, whether you need correction for nearsightedness, farsightedness, astigmatism, or a combination of these issues.

Long-Lasting Results: Once an IOL is implanted, it becomes a permanent part of your eye and provides clear vision for the long term. This means that the benefits of cataract surgery extend well beyond the immediate post-operative period.


Cataract surgery with a lens implant (IOL) is an amazing procedure that can significantly improve your vision and quality of life. It is essential to work closely with us to select the right IOL for your individual needs. With the right choice, you can enjoy the clarity of vision, reduced dependence on glasses, and an improved quality of life. However, some of the lens implants (IOL) are not covered by health insurance.  You will need to pay out-of-pocket for certain types of lens implants (IOLs).   We can help you select the type of lens implant that suits both your needs and budget. 



Spooky Eye Facts

Spooky Eye Facts

As Halloween approaches here are some spooky eye facts:


  • The Cornea Can survive without blood: The cornea, the outermost layer of the eye,  lacks blood vessels, receiving nutrients and oxygen directly from tears and aqueous humor.
  • The Blind Spot: Each eye has a blind spot where the optic nerve exits the retina. Your brain compensates for this blind spot by filling in the missing information, creating an illusion.
  • Phantom Limb Sensation: After losing an eye, some people experience “phantom eye” sensations, similar to the more commonly known “phantom limb” phenomenon in amputees.
  • Visual Snow: Some people have a condition called “visual snow,” where they see what looks like visual noise superimposed over their normal vision, making for a spooky and unsettling experience.

More Spooky Eye Facts!


  • Optic Illusions: Optical illusions like the “hollow mask illusion” can make a concave object (like the inside of a mask) appear convex and spooky.
  • Brain Tumors:  Brain tumors can cause unsettling visual hallucinations.  This is called Charles Bonnet Syndrome.
  • Red-Eye Effect: The red-eye effect in photos occurs when the flash reflects off the blood vessels in the retina, giving a creepy, glowing appearance to the eyes.
  • Mirror Gazing: Staring into a mirror in a dimly lit room might reveal spooky or supernatural phenomena, leading to the creation of the Bloody Mary legend.
  • Parasitic Eye Worms: Certain parasitic worms can infect the human eye, leading to visual disturbances and discomfort. A horrifying thought, even if it’s relatively rare.
  • Ghost Images: The “Palinopsia” phenomenon can make previously seen images linger in your vision, creating ghostly and unsettling visuals.
  • Heterochromia: Heterochromia is a condition where a person’s eyes are different colors, which can be striking and eerie.

These spooky aspects of the human eye can certainly make it a subject of fascination and sometimes even fear. 





Is LASIK safer than long-term Contact Lens Wear?

Is LASIK safer than long-term Contact Lens Wear?

Is LASIK safer than long-term contact lens wear?

Contact lenses have long been a convenient option for vision correction. However, over time, the risks associated with long-term contact lens wear have become increasingly evident. Studies have found that LASIK (Laser-Assisted In Situ Keratomileusis) surgery is potentially safer alternative compared to extended contact lens use.

The Downsides of Long-Term Contact Lens Wear

  • Increased Risk of Infections: Contact lens wearers are more susceptible to eye infections than non-wearers. Many studies have that found that the risk of microbial keratitis, a potentially sight-threatening eye infection, was amazingly up to 180 times higher in contact lens wearers than in those who underwent LASIK.
  • Corneal Neovascularization: Long-term contact lens use can lead to a condition known as corneal neovascularization, where blood vessels start growing into the cornea. This can disrupt the cornea’s clarity and oxygen supply, potentially causing discomfort and vision problems.
  • Corneal Scarring: The constant friction between contact lenses and the cornea can result in micro-trauma, leading to corneal scarring over time. Corneal scarring may affect visual acuity and quality, making it difficult for contact lens wearers to achieve optimal vision
  • Giant Papillary Conjunctivitis (GPC): GPC is another condition associated with contact lens wear. It is characterized by inflammation of the conjunctiva, the clear tissue covering the white part of the eye. GPC can lead to itching, discomfort, and blurred vision, making it uncomfortable for contact lens wearers.

The Safety of LASIK Surgery

LASIK, on the other hand, offers a promising solution to these long-term risks associated with contact lenses:

  • Reduced Risk of Infections: According to the American Society of Cataract and Refractive Surgery (ASCRS), LASIK surgery carries a minimal risk of infection due to the absence of foreign bodies (i.e., contact lenses) interacting with the eye surface. The flap created during LASIK heals quickly, reducing the likelihood of microbial keratitis.
  • No Corneal Neovascularization: LASIK reshapes the cornea to correct vision, eliminating the need for contact lenses. Consequently, LASIK patients do not experience corneal neovascularization associated with prolonged lens wear, ensuring a clear and healthy cornea.
  • Minimal Risk of Corneal Scarring: While LASIK does involve corneal reshaping, the procedure is performed with utmost precision, minimizing trauma to the cornea. This precision means that corneal scarring is exceedingly rare in LASIK patients.
  • Avoidance of GPC: LASIK eliminates the need for contact lens wear altogether, thus completely avoiding the risk of GPC and the associated discomfort and vision problems.


While both long-term contact lens wear and LASIK offer vision correction, the risks associated with contact lenses over time are becoming increasingly evident. LASIK surgery, backed by advanced technology and precision, provides a safer and more convenient alternative. It reduces the chances of eye infections, corneal neovascularization, corneal scarring, and conditions like GPC that contact lens wearers may face.

Before making a decision, it is important to consult with and eye doctor. The doctor needs to assess your unique circumstances and recommend the most suitable vision correction option for your needs. It is important to ensure that you are a good candidate for LASIK and/ or contact lenses. When considering LASIK, choose an experienced surgeon and adhere to the post-operative care instructions for the best results.






Monovision Cataract Surgery

Monovision Cataract Surgery


Monovision cataract surgery is gaining popularity as an option to reduce dependence on glasses. However, it’s important to note that there can be potential side effects and issues associated with monovision.  Let’s explore both its advantages and disadvantages.

Understanding Cataracts

Let’s begin by understanding what a cataract is and how it can be addressed. Cataracts are a prevalent age-related eye condition that can substantially diminish vision and overall quality of life. Cataracts occur when the eye’s natural lens, situated behind the pupil, becomes cloudy. This cloudiness can result in vision loss, making tasks such as reading, driving, and everyday activities challenging. To fix this problem, cataract surgery becomes necessary.

What is Cataract Surgery?

Cataract surgery is one of the most common and successful surgical procedures worldwide. During this surgery,  your cloudy lens is removed and replaced with an intraocular lens (IOL) to restore clear vision.  You can choose from various types of IOLs, each designed to meet specific visual needs.

What Is Monovision Cataract Surgery?

Monovision cataract surgery can give you the ability to see clearly at multiple distances.  This helps reduce your dependence on glasses or contact lenses.  It is most successful if you have been using monovision contact lenses or have had monovision LASIK (laser-assisted in situ keratomileusis).

The Role of Astigmatism Correction

A critical aspect of successful monovision cataract surgery is the correction of astigmatism.  Astigmatism is a common refractive problem caused by a slightly irregular shaped eye, leading to blurred or distorted vision. When undergoing monovision cataract surgery, it’s essential that any existing astigmatism is corrected to achieve the best possible visual outcomes.  Astigmatism can blur both near and distance vision.

How Does Monovision Cataract Surgery Work?

In monovision cataract surgery, the intraocular lenses (IOLs) are strategically implanted in each eye. One eye is adjusted for distance vision, while the other is fine-tuned for near vision. This intentional disparity in your vision provides you with the capability to focus on objects both nearby and far away. However, it’s crucial to strike the right balance and avoid excessive disparity, as an extreme imbalance can hinder your brain’s ability to adapt effectively.

Benefits of Monovision Cataract Surgery

  • Reduced Dependence on Glasses: A significant advantage of monovision cataract surgery is the reduced need for glasses in your daily activities. Reading and using your smartphone may become easier without requiring reading glasses.
  • Enhanced Quality of Life: Monovision cataract surgery provides the freedom to enjoy various activities without the hassle of switching between reading and distance glasses.
  • Proven Track Record: Monovision has a long history of successful use in contact lenses and surgeries like LASIK.

Disadvantages of Monovision Cataract Surgery

  • Reduced Depth Perception: There might be a slight reduction in depth perception due to the varying focusing abilities of each eye. This can impact activities such as flying, operating cranes, and certain sports that demand precise distance vision.
  • Adaptation Period: Adjusting to monovision can take time, and you may feel uncomfortable with the sensation of having one eye focused on near objects and the other on distant objects.
  • Not Suitable for Everyone: Monovision may not be suitable for you with certain medical eye conditions or particular visual requirements, such as pilots, military personnel, or truck drivers.


Monovision cataract surgery, coupled with astigmatism correction, can reduce your reliance on glasses or contacts, offering convenience and a better quality of life. To decide if it’s suitable for you, consult an experienced cataract surgeon. Like any medical procedure, it is important to have a detailed discussion about potential benefits, risks, and side effects.





Monovision LASIK

Monovision LASIK

Monovision LASIK

Monovision LASIK, is simply correcting one eye for distance and one eye for near vision.  The eye corrected for distance vision is usually the dominant eye and the non-dominant is eye corrected for near vision.  If you are right-handed usually your right eye is your dominant eye, but not always.   Why would you want to do this?  If you are over 40 years old you will have developed presbyopia; therefore, you may need reading glasses for up close vision.  Presbyopia is the inability to focus far and near as the lens in your eye ages.  While Monovision LASIK offers advantages, it is essential to weigh these against potential drawbacks to make an informed decision. I will explain the pros and cons of Monovision LASIK.

Pros of Monovision LASIK

Reduced Dependence on Reading Glasses: One of the primary benefits of Monovision LASIK is its potential to reduce or eliminate the need for reading glasses. If you are over 40 years old you will need reading glasses – if both eyes are corrected for distance.  By optimizing one eye for close-up tasks, you can perform everyday activities without the constant use of reading glasses.  Otherwise you would need reading glasses for reading books, smartphones, any possibly working on a computer.

Quick and Painless Procedure: Like traditional LASIK, Monovision LASIK is a swift and virtually painless procedure. It typically involves the use of advanced laser technology to reshape the cornea, allowing for efficient vision correction. You can often return to their daily activities shortly after the surgery.

Proven Efficacy: Monovision LASIK has a strong track record of delivering effective results. Numerous studies have shown that a significant percentage of patients who undergo this procedure achieve improved near vision, with some attaining near acuity of 20/40 or better.

Best candidates:  The best candidates for LASIK monovision are patients that have monovision with their contact lenses, and like it.

Cons of Monovision LASIK

Distance Vision:  Your distance vision will not be quite as sharp because only one eye is correct for distance.  You also lose some depth perception.

Adjustment Challenges: One of the potential drawbacks of Monovision LASIK is adapting to the eye imbalance created by the procedure.  You may experience initial discomfort, visual disturbances, or difficulty coordinating their vision between the two eyes.

Extended Recovery Period: Compared to traditional LASIK, the recovery period for Monovision LASIK may be longer.  You may encounter issues such as reduced night vision, decreased depth perception, or blurry vision for either near or distant objects. These side effects can persist for some time during the recovery process.

Occupational Considerations: Certain professions that demand excellent depth perception may not be suited for Monovision LASIK. Individuals in such careers, including pilots, professional athletes, and truck drivers, may find that the procedure does not align with their occupational requirements.

Reversibility Challenges: While Monovision LASIK is reversible, the process may not always yield the desired results, and the return to a balanced vision may not be as straightforward as the initial procedure.  You should carefully consider this before opting for Monovision LASIK.


In conclusion, Monovision LASIK offers several advantages, primarily in reducing the reliance on reading glasses and providing a quick and relatively painless vision correction process. However, it also presents challenges, such as adjustment difficulties, an extended recovery period with potential visual disturbances, and occupational constraints for certain individuals. The decision to undergo Monovision LASIK should be made after a thorough discussion with your doctor.  You need to take into account your specific needs, lifestyle, and expectations. While Monovision LASIK can be a valuable solution for most, it is essential to be aware of both its benefits and drawbacks to make an informed choice about this vision correction option.
