LASIK and reading glasses

LASIK and reading glasses

For patients who have specific refractive defects, such as nearsightedness, LASIK is a common vision correction procedure that may help them see better. If you are looking for a solution that will allow you to get rid of your reading glasses, it makes sense to consider LASIK surgery. Can LASIK, on the other hand, genuinely fix presbyopia?

Is it possible to have LASIK done and have my need for reading glasses eliminated?

It is possible that LASIK will be a good option for people who are seeking treatment for nearsightedness or other common refractive errors. However, it is not intended to be used in the treatment of presbyopia. While LASIK works by reshaping the cornea, presbyopia, or the loss of close vision, occurs as a consequence of changes in the lens of the eye. Even if you had a surgery lasik treatment while you were in your 20s that allowed you to be free of glasses and contacts, you may still need reading glasses in your 40s or 50s. 2

Presbyopia can be treated by a procedure known as monovision LASIK, which is offered by some eye doctors. An example of this would be a monovision procedure, where one eye is corrected for distant vision and the other for close vision. Due to the fact that monovision is dependent on the brain’s capacity to adapt to it, it is not effective for everyone. After the age of 40, many patients also have dry eye symptoms, and LASIK has been reported to exacerbate dry eye symptoms in certain individuals. This off-label use of LASIK for the treatment of presbyopia is not approved by the FDA, and there is limited information on how effective it is in treating patients with presbyopia in this population.

Understanding the Causes of Age-Related Near Vision Impairment

As we grow older, the lens of the eye begins to stiffen and change shape, a natural process that causes a type of near vision loss known as presbyopia 1 to develop gradually. A common occurrence among people over the age of 40 is the tendency to hold items such as phones or books further away from their bodies or to squint when reading small print. Presbyopia is the most common cause of this difficulty in seeing things up close and personal. Although there is no way to avoid it, presbyopia affects everyone at some point in their lives. Reading glasses are the most popular therapy for it.

Treatments for Presbyopia are available.

The most frequent method of correcting presbyopia is using reading glasses. Many individuals, however, do not like the way they seem while they are wearing reading glasses, and they are bothered by the inconvenience of having to put their readers on and take them off during the day.

Exchange of Refractive Lenses (RLE)

The refractive lens exchange procedure (also known as RLE) is a type of vision correction procedure that is sometimes used to treat presbyopia. RLE is a procedure that includes replacing the natural lens of the eye with an artificial intraocular lens implant, using techniques that are basically the same as cataract surgery (IOL). Some kinds of premium IOLs, such as multifocal or trifocal lenses, may help to improve presbyopia and lessen the need for reading glasses in older patients. 

The FDA has authorized intraocular lenses (IOLs) as a medical device for the treatment of cataracts, however they are not meant to be used to correct presbyopia as a main function. Since RLE is an off-label usage of IOLs, there is minimal evidence available. However, some specialists are concerned about postoperative side effects, which may vary from visual abnormalities such as halos and glare to more significant issues such as retinal detachment.

Are you over the age of 40 and finding it difficult to see tiny text with your glasses or lenses? LASIK is a procedure that may assist with this.

Modern LASIK surgery can correct reading vision problems caused by presbyopia using a technique known as monovision. In this procedure, the LASIK surgeon completely corrects the refractive errors in one eye while intentionally leaving the other eye mildly nearsighted, resulting in improved reading vision. As a consequence, the completely corrected eye sees far things extremely well, while the nearsighted eye gives better close vision without the need for reading glasses.

In most cases, if you are contemplating this option, it is best to first experiment with monovision using contact lenses for a short length of time to ensure that you can adjust to the monovision experience before going with monovision LASIK surgery.

Another alternative is multifocal LASIK, which is a surgery in which a laser is used to reshape the surface of the eye in a way that replicates the look of bifocal or multifocal contact lenses, respectively. The use of multifocal LASIK may lessen the need for reading glasses, but there is a higher risk of glare and halos following the treatment, which may be difficult to correct.

LASIK monovision is a procedure that may be used to enhance reading vision. Another option is a corneal inlay.

Another type of presbyopia correction surgery is corneal inlay surgery, which is a relatively new procedure. It is possible to perform this procedure using a laser to create a small pocket in the center of the cornea of one eye, and then place a small optical device (a corneal inlay or corneal implant) in this pocket, which then self-seals.

The corneal implant enhances the depth of focus in the treated eye, resulting in improved close vision while no substantial loss of far vision is experienced by the patient. For this reason, it is preferable to monovision LASIK, which improves near vision but causes significant blurring and distortion of distance vision in the “near” eye.

The Kamra corneal inlay is the only corneal inlay approved by the FDA for use in the United States to improve reading vision at this time (AcuFocus). A second corneal inlay, the Raindrop Near Vision Inlay (ReVision Optics), was approved by the FDA in 2016 but was subsequently withdrawn from the market in January 2018.

Another corneal inlay, the Presbia Flexivue Microlens (Presbia), has gained the CE mark, enabling it to be sold commercially across Europe; however, it has not yet been authorized for use in the United States by the Food and Drug Administration. [Learn more about corneal inlays in this article.]

In some cases, a corneal inlay procedure can be performed for people who have perfect distance vision without the use of corrective lenses and only require assistance with reading vision problems caused by presbyopia. Alternatively, it may be done at a later date following LASIK for those who need vision correction for nearsightedness, farsightedness, and/or astigmatism in addition to LASIK.

Finally, if you have been diagnosed with early cataracts (or if you are at high risk for developing cataracts as a result of your age or other factors), refractive lens exchange or early cataract surgery, which includes the implantation of a modern presbyopia-correcting intraocular lens (IOL), is an excellent option.

Due to the variety of alternatives available, it is recommended that you visit with your eye doctor to identify which surgical surgery to enhance your reading vision is the most appropriate for you.

The laser eye surgery treatment is one of the most frequently done forms of laser eye surgery today. It is used to correct a wide variety of visual problems, including astigmatism, farsightedness, and nearsightedness. Many individuals, understandably, have concerns about this process, with “Are you awake during laser eye surgery?” being one of the most commonly questioned.

Yes, you will be awake throughout the lasik eye surgery treatment. Certain individuals think that since they are receiving a medical treatment, they will be sedated and put to sleep. Despite this, laser surgery, unlike other forms of surgery, takes only a few minutes to accomplish.

You are also not need to be awake. Your laser eye surgeon will numb the eyes with local anaesthetic eye drops prior to performing the laser surgery. To assist you in relaxing and putting you at rest, your surgical team will explain what they are doing while they do the procedure.

The overall time required to complete both eyes is not long. Many individuals are astonished at how quick, painless, and quick the laser eye surgery process was and, even if they had qualms or anxieties prior to the treatment, they are pleased they had it done. They will frequently never have to bother about contacts or glasses again!

What Happens If I Move or Blink During LAISK Eye Surgery?

While some may anticipate lasers blasting out of the ceiling and spinning out of control if they move, cough, sneeze, or even blink, the procedure is not nearly as frightening as their imaginations suggest. To begin, you will lie comfortably with your head supported.

Following that, your laser eye surgeon will secure the eyelid in place and out of the way with a unique blinking retainer. You have nothing to fear, thanks to their state-of-the-art laser eye surgery technology, which can track the eye’s motions at rates of 4,000+ times per second.

Your laser eye surgeon’s surgical equipment is extremely precise and accurate. Laser eye surgery is one of the most effective surgical procedures available today, with low risks and few adverse effects. Your LASIK eye surgery will be completed in the time it takes for you to think about what may go wrong.

What to Expect in the Post-Operative Period

Following that, you may notice your eyesight becoming foggy or fuzzy. This is quite typical. Within the following 24 to 48 hours, your eyesight will begin to improve. The next day, a follow-up visit is scheduled to check your eyesight and confirm that everything is developing as planned.

Following your eye surgeon’s instructions and using any recommended drugs or eye drops as advised is a necessary part of your rehabilitation. You should refrain from rubbing or touching your eyes until they have healed.

You may even be astonished to find that your vision has improved to 20/20 or, in some circumstances, even better at follow-up sessions. However, not everyone gets this amount of improvement due to a number of variables such as present visual difficulties, overall health, and so on.

What are the various causes of a patient’s eyesight deteriorating following laser eye surgery?

Several of the causes are quite uncommon. Others are more prevalent. Numerous are almost certain. The majority may be discovered prior to surgery using appropriate screening tests:

1. Presbyopia: 

This is the primary one that is assured. When we are children, the lens of the eye is capable of focusing both far and near. At the age of 40, the lens becomes less flexible, and near vision steadily deteriorates. This is why individuals over the age of 40 use reading glasses, bifocals, or trifocals to see clearly up close. A remedy for this is a procedure called Monovision laser eye surgery, which corrects one eye for distant vision and the other eye for near vision.

2. Cataracts:

This is the second and absolutely certain explanation. All humans, if they live long enough, will acquire cataracts as a natural part of the aging process. This is a lens clouding that causes blurry, hazy vision and is related with visual disturbances such as glare, starbursts, and haloes. Fortunately, this may be resolved with Cataract surgery. With the introduction of new multifocal lens implants, such as the ReSTOR and Crystalens, vision may be corrected for both near and far, hence obviating reason #1.

3. Progressive Myopia: 

Know this before going laser eye surgery

Nearsightedness often stops growing in the early twenties. Myopia can proceed to the 40’s or 50’s in certain cases. If your nearsightedness worsens following laser eye surgery, your vision will become blurry. To treat residual myopia, an enhancement surgery may be required.

4. Farsightedness: 

Laser eye surgery is more difficult to perform on farsighted individuals than on nearsighted people. Farsightedness often worsens with age in the majority of sufferers. Patients who are farsighted are more prone to require enhancement surgery.

5. Keratoconus Types: 

Keratoconus is a congenital corneal condition that causes gradual corneal thinning and increased astigmatism. Patients suffering from full-blown Keratoconus patients should never get laser eye surgery, since it will exacerbate the illness. Regrettably, there is no accurate test for diagnosing subclinical forms of the disease at the moment. Risk stratification is the only solution. If you are at risk of developing subclinical Keratoconus, you have two options: PRK or no Corneal surgery. Corneal transplantation can be used to treat patients with symptomatic Keratoconus.

6. Swollen Eyes: 

Know this before going laser eye surgery

When the LASIK flap is created, the nerves that feed the cornea are briefly disrupted. Typically, these nerves regrow within the first 3-6 months following laser eye surgery. During this time period, the eyes tend to be dry, which might result in hazy or fluctuating vision. If your eyes are dry prior to laser eye surgery, you may require intensive dry eye treatment with punctual plugs or ReSTASIS eyedrops. Another possibility is to try PRK, which is less drying. Patients who suffer from extremely dry eyes or collagen vascular illnesses such as Sjogren’s syndrome or rheumatoid arthritis should avoid laser eye surgery. Additional tips may be found in our Dry Eye page.

7. Huge Pupils: 

When we are children, our pupils are large. They gradually lose size as they mature. It is hypothesized that having huge individuals may enhance the chance of patients developing visual problems.

8. Diabetes: 

Know this before going laser eye surgery

If you get diabetes later in life, your eye prescription may alter. If blood sugar levels stay excessive for an extended period of time, it can result in damage to the retina known as Diabetic Retinopathy. Diabetic retinopathy is the leading cause of blindness in working-age people. Fortunately, if blood sugars are immediately managed, the eye prescription returns to normal.

9. Macular Degeneration: 

As people age, they are at an increased risk of developing a condition called macular degeneration.

10. Other Eye Diseases: 

Laser eye surgery does not confer immunity from eye illness. Laser eye surgery patients continue to be at risk for eye problems that might cause blindness or vision loss in non-LASIK patients.
