Monovision Iols Vs Multifocal Iols

The first ever intraocular lens (IOL) was successfully implanted in a patient at St Thomas Hospital in London by Sir Harold Ridley on 29th November 1949 and ever since surgeons have discussed and researched the best surgical lenses to use. A staggering 67 years later, and with huge advances in the technique of implanting an intraocular lens and the lenses themselves, the discussions continue. Now we are debating monovision IOL implants versus multifocal IOL implants for presbyopia.

An intraocular lens implant is mostly used in older adult patients who have developed cataracts or myopia. IOLs are implanted in the eyes and can be offered in a monovision or multifocal variation. Each type of lens has its own assets and flaws. The eye doctor/surgeon will always recommend what they think is the best and safest lens for you, as what is good for you may not be for someone else. In this article I will go through the differences between monovision and multifocal IOL implants.

Monovision IOL Implants

Monovision is one of the ways we can treat presbyopia, in which we implant a monofocal IOL in both eyes but not the same way. An IOL can be implanted so to give near, intermediate or distance vision. When we carry out a monovision implant procedure one eye is corrected for distance vision and the other eye is corrected for near or intermediate vision.

This might appear to be problematic at first but your brain is able to do something extraordinary when eyes are corrected with monovision implants. The eye that is corrected to give distance vision will give the distance image to the brain, while the other eye, which is corrected to give closer vision, will give that image to the brain and the brain is able to merge the two together to make a whole. This may take a little while to get used to and for the brain to adjust to the new monovision at first. The eye clinic can normally demonstrate this to you to see how you cope with this effect.

Due to the fact that the monofocal monovision implants do not split light entering the eye they are better for night driving as you do not get as much glare and halos from light as patients with multifocal implants. Also as you have a fixed focal point on each eye with monovision, they tend to perform better with intermediate vision, such as using a computer. The downside to monovision is that it is a compromise and some people will love the effect while others are unable to get along with it.

Multifocal IOL Implants

Unlike monovision IOL implants where each eye has one focal point, multifocal implants work like a progressive lens. On a multifocal implant the lens itself has many circles around it at different points to give distance, intermediate and near vision in both eyes the same. The circles on the multifocal implants splits light entering the eyes so you can focus on whichever distance you are looking at, whether that be close up or an object in the distance. The point of a multifocal implant is so you will not require the use of glasses or visual aids during your day-to-day activities. Just like the monovision implants, multifocal implants take a little time to get used to. The brain will need to relearn to find the correct point for near, middle and far distances.

What Is The Mandela Effect

So what is the Mandela effect? It is a phenomenon that more and more people are beginning to witness and it is disturbing. has to do with separate time steams, or parallel worlds. But it’s not as cut and dried as that. The effect is named after Nelson Mandela. Many people remember Nelson Mandela dying back in the 1980s during his imprisonment. Yet according to what we know today, he was released from prison, became President of South Africa, and died in 2013.

So which is the correct story? Apparently both are. People across the globe are now realizing that their memories of certain events have dramatic differences. The theory is that our society has become split between those who have one set of connection memories and those who have an entirely different recollection. This suggests the idea of a quantum split or jump in space-time. And it is not just related to Nelson Mandela. There are many examples of things changing from what many people have remembered. Let me present just a few:

In 1984 Prince released his song Let’s Go Crazy. Many remember the words Dearly beloved/We are gathered here today/To celebrate this thing called life. But if you research the lyrics, instead of the word celebrate, it says, To get through’ this thing called life. What do you recall?

Do you remember the children’s characters the Berenstain Bears, created by Stan and Jan Berenstain? Well, many remember them being called the Berenstein Bears, not the Berenstain Bears. What do you remember?

Tank Boy, as he has become known, was run over by a tank in Tiananmen Square. Many remember the bloody event. However, if you look at footage of the incident, he wasn’t actually run over”yet many remember his death vividly.

If you have seen Disney’s Snow White, you may be among those who remember the witch going to the mirror and saying: Mirror, Mirror, on the wall/Who’s the fairest of them all? Unfortunately, that’s not what she says. It’s Magic Mirror, on the wall

How about Ann Rice’s Interview with a Vampire? That’s how many of us remember the title. But the actual title is now Interview with the Vampire. Strange, right?

So what is going on here? This phenomenon is only now gaining momentum, and more and more people are starting to notice it. Some say it is being caused by CERN (the European Organization for Nuclear Research) and its Large Hadron Collider. The idea here is that the government, in a black operations experiment, is trying to open the door to a parallel world, which is causing havoc in the space-time continuum, thus producing the Mandela Effect. But here is what I believe is taking place. (And get ready, because I’m about to take you out of the Matrix!)

The Importance Of Correct Retinitis Pigmentosa

The photoreceptor cells comprise of rods and cones and the symptoms of Retinitis pigmentosa depend on what kind of photoreceptor cells are involved. In most cases, the rods are affected first. Rods are present in the outer layer of the retina and this is where Retinitis pigmentosa usually begins. When this happens, individuals will find it tough to focus on objects in dim light. This disease slowly spreads out further and takes up the central vision of the eyes.

If you have a family history of Retinitis pigmentosa, then you should get your eyes checked from time to time. Night blindness is one of the most common symptoms in early Retinitis pigmentosa. However, if the cone has been disrupted then an individual will find it tough to identify colors.

Retinitis pigmentosa is a progressive disorder which can be identified at a young age. This condition is usually observed in adolescents and young adults.The degree of the intensity of this condition varies from person to person. However, most people suffering from Retinitis pigmentosa turn blind by the age of 40. It is more common for men to get affected from Retinitis pigmentosa in comparison to women.

Retinitis pigmentosa is a genetic disease which is passed on from one generation to another. It is ususally passed on from the parents, so if you or your partner suffers from Retinitis pigmentosa, you need to consult your doctor about the possibility of your child getting it.

There are a number of methods for successful Retinitis pigmentosa treatment in India. It is essential you consult a doctor who is experienced and well trained to handle this condition.

Since this is a genetic condition, you can take various precautions to prevent your child from getting it. You need to remember that Retinitis pigmentosa can be treated and controlled, but there is no way you can cure it. Proper care and timely checkups are crucial since they help control the loss of vision to a great extent. Studies prove that the right medication can help prevent parents from transferring this disease to their children.

Those suffering from Retinitis pigmentosa can consider undergoing surgical treatments in order to treat the condition. There are various kinds of surgical procedures available that help control the condition to a great extent. Since this condition usually affects a person in the early years of their lives, regular eye checkups can help to a great extent. Always consult a good eye doctor who can prescribe the correct eye medication to help improve the condition. These doctors can also guide Retinitis pigmentosa patients about the various surgical procedures that can help them.

Wearing Your Contact Lenses

Before you touch your lenses, either to put them in or take them out, you should wash your hands using a mild soap, ideally fragrance and oil free. You should make sure you dry your hands thoroughly with a lint free towel to avoid any small debris getting it your eyes.

How to Put in and Take Out Your Contact Lenses

Wash your hands as advised above. Try to start with the same eye every time you insert or remove your lenses, this should minimise the risk of you putting the wrong lens in the wrong eye. Slide the lens of out the packet or case onto the palm of your hand using your finger. If you have been advised to rinse your lenses with solution by your eye doctor or eye clinic do this now, then place the lens on the tip of your index finger. While holding your lower lid down, with the same hand the lens is on, and using the other hand to hold up the upper lid, gently place the lens on the surface of your eye. Let go of your lids carefully and blink a few times.

When it comes to removing soft contacts, you should hold down your lower lid and look to the side or up, then carefully move the lens to the white part of your eye. Then use your thumb and index finger to pinch the lens and lift it off of the eye. If you wear gas permeable contact lenses you should remove them by opening your eyes wide and pull the skin which is near the corner of your eye nearest to your ear, then bend over the palm of your hand and take a blink, the lens should pop out and land in the palm of your hand.

Remember that your eye clinic should show you how to insert and remove contact lenses and let you practice before you leave the clinic.

How to Clean and Store Your Lenses

There are lots of ways you can clean your lenses. Remember to always follow the advice of your eye clinic or optician and never reuse daily disposable contacts. You can get a multipurpose solution which enables you to clean, rinse, disinfect, and store your lenses all with only one solution. You can also get separate solutions for cleaning and rinsing. Another option is with hydrogen peroxide solution, you leave your lenses in a basket which submerges them in the solution, but you should never use this solution to rinse your lenses in. You should also clean your lens case with a disinfectant solution every night and dry carefully and replace your case at least every 3 months.

Never use water to rinse or clean your contact lenses. Water contains many microbes which can cause serious infections to your eyes.

If you are thinking of starting to use contact lenses or are having a problem with your current ones you should always visit your eye clinic, eye doctor or optician to ask for advice. Never purchase contact lenses online if you have not seen a specialist first or used contact lenses before, misuse of lenses can lead to serious eye problems and infections.
