Are intraocular lens really effective for high myopia rate patients (-15)? Are there different types of these intraocular lenses for myopia? Risky?

Yes: Implant choices: Best intraocular (IOL) choice: Depends on if you want good reading, computer, distance vision OR all distances after surgery; if you have astigmatism (may need Toric IOL). If you want good reading, intermediate, distance VA, Multifocal or Crystalens may be option. Full answer: Cataract Surgery Options at eyedoc2020.blogspot. Com. ...Read more

What are ortho-k lenses used for: myopia (nearsightedness) or astigmatism?

What are ortho-k lenses used for: myopia (nearsightedness) or astigmatism?

Both: Ortho-k is an expensive and non-sensible treatment. With this, you wear contact lenses while you sleep that mould the cornea. This allows better vision. During the day, the cornea reshapes itself to normal. What this means is that you see well for a few hours and your vision fades as the day progresses. A more sensible and cheaper solution is to wear contact lenses during the day. ...Read more

Could myopia reverse when using convex lens (magnifying lens).?

No: Lenses do not change the eye. A convex lens would be the opposite of what a myope needs which is a concave lens. ...Read more

Will lenses with a small positive value like say +0.5 help reverse some degree of myopia over time?

Will lenses with a small positive value like say +0.5 help reverse some degree of myopia over time?

No effect: Myopia is unaffected by whether or not you wear corrective lenses or contacts. If you have some amount of myopia, wearing a +0.5 lense will simply give you a longer time with blurred vision. ...Read more

Hi what's the side effect of conatact lens for myopia? Ist bad? For how many hours I have to wear them?

Hi what's the side effect of conatact lens for myopia? Ist bad? For how many hours I have to wear them?

Should be none: Contact lenses are a substitute for eyeglass correction. When properly fit and with the proper power, you should see well and there should be no side effects if you keep the schedule prescribed. Always remove the lenses if the eye (s) gets red and replace them according to schedule and there should be no issues. Wear them as long as you need good vision within the proper schedule. ...Read more

My contact lens Rx is -3.75 BC 8.8 DIA 14.0 (left) & -3.50 BC 8.8 DIA (right). What does that mean in terms of myopia severity & Rx strength? Curious.

My contact lens Rx is -3.75 BC 8.8 DIA 14.0 (left) & -3.50 BC 8.8 DIA (right). What does that mean in terms of myopia severity & Rx strength? Curious.

Myopia: Your degree of nearsightedness is mild-moderate level. Your contact lens prescription indicates this -3.50 OD (right), -3.75 OS (left). The BC is the base curve of contact which is the curvature measurement in milimeters of the back of the contact (smaller the number the more curved or steeper your cornea). The diameter is how wide the contact is and how it will rest on your eye. ...Read more

Do the hard contact lenses affect the speed of the myopia?

Do the hard contact lenses affect the speed of the myopia?

No effect: Well fitted contact lenses should be comfortable and the vision should be fine. This will not change the power of the eye nor the speed of the progression of the myopia if that is going to occur. ...Read more

Can plus lens therapy reverse/cure myopia? I'm seeing improvement with that, if it can't then why its improving mine?

Can plus lens therapy reverse/cure myopia? I'm seeing improvement with that, if it can't then why its improving mine?

May be temporary: Myopia is usually caused by an abnormally shaped eyeball. Since it's a structural abnormality, using a lens wouldn't be expected to permanently cure it. It's possible that the lens may be training you to focus better for short periods of time, I suppose, but the only cure for myopia that I'm aware of is surgery. Perhaps one of my opthalmology colleages might have more info for you. ...Read more

Can plus lens therapy reverse/cure myopia? I'm seeing improvements with that and many peoples have reversed theire myopia too.

No: Plus lens therapy has no scientific validity, nor does it make sense. Like many types of vision therapy techniques, there is no study data to support its use. Beware of snake oil salesmen! ...Read more

Is progression of myopia controlled by wearing glasses or contact lenses?

Is progression of myopia controlled by wearing glasses or contact lenses?

No: There is not a way to stop the progression of myopia. The eyeballs grow very little after early childhood, but even a slight changes in the shape of eyeballs can increase myopia. A one gets older, the eyeballs will finally stop changing, but that may be in his 20's or 30's. ...Read more

Can implantable contact lenses be used for severe myopia? I am very nearsighted, and I've been told that laser surgery might not be completely effective because of this. I don't want to undergo surgery if it won't give me 20/20 vision. Would implantable c

If: If you are not a good candidate for lasik, the alternatives are the implantable contact lens or a lensectomy. The latter is essentially a cataract surgery before the eye's natural lens has developed a cataract. Naturally there are pros and cons to these refractive surgeries. While it is impossible to guarantee an uncorrected visual acuity of 20/20 with any refractive surgery, most patients are very pleased with their result. ...Read more

I have a corrective lens prescription for myopia. How do I derive the intermediate (computer) distance from a D.V. prescription?

I have a corrective lens prescription for myopia. How do I derive the intermediate (computer) distance from a D.V. prescription?

Add a little plus: In most cases the prescription will be for distance indicating some degree of minus power. To adjust for computer screen distance, add +1.25 to this power and that usually works. Note however, that the pupillary distance (the space between each eye) is set for distance viewing (usually 57-63 mm) and needs to be adjusted closer for viewing of a video screen. ...Read more

Is there any natural way to improve weak eyesight (myopia)beside glass correction or surgery??? Plus lens therapy??

Is there any natural way to improve weak eyesight (myopia)beside glass correction or surgery??? Plus lens therapy??

I don't know of any: Sadly, unless you have an eye disease such as glaucoma, correction of your vision can only be done with one of these. If the eye problem is of new onset, you should definitely have your eye pressure checked, to prevent glaucoma or another disease from taking your vision altogether. ...Read more
