Astigmatism Vs Myopia
Toric IOLs: The Crystalens and Trulign are high tech intraocular lenses called presbyopia-correcting or "premium" IOLs. Crystalens for those who have both cataracts and hyperopia, which causes near vision problems. The Trulign Toric IOL best suited to people who have astigmatism and wish to have improved uncorrected near, intermediate and distance vision after cataract surgery. Be prepared for side effects ...Read more
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
Trouble Seeing Far: Myopia occurs in many people and means you have problems seeing far away but usually don't have trouble reading or seeing things closer to you. Typically it can't be prevented and occurs when the eye becomes a bit more oval or longer in shape. Any changes in vision should be evaluated by a doctor to be sure that it's not something more severe or dangerous. For example, diabetes can affect vision. ...Read moreSee 2 more doctor answers
Astigmatism correctn: Absolutely. The vast majority of corneal refractive surgery, i.e. Lasik or surface ablation/prk, is for just that. Most people wearing glasses for distance vision are myopic, and most of them have some amount of astigmatism as well. Today's lasers can correct a very high proportion of your myopia and your astigmatism. Some lasik surgeons give free educational appointments or seminars. ...Read more
Myopia: Nearsightedness or myopia is very common. It is not uncommon for us to see patients who are -10 diopters or more. Be sure you have a dilated retinal exam every year and you know what retinal detachment signs look like (burst of black floaters, flashing lights, new floaters, curtain coming down over your vision); consider polycarbonate glasses for protection especially during sports. ...Read moreSee 1 more doctor answer
Probably polycarb: Polycarbonate lenses are "high index" lenses . They are often used in high myopes to allow for the glasses to be thinner and lighter. They do have more chromatic aberration though. Discuss the various pros and cons with your optician before deciding what it right for you. ...Read more
Hyperopia: If the eye from front to back is too short, so that the lens and cornea cannot focus the light inside the eye (too weak), the correction for this is to supply a magnifying lens in the eyeglasses. The lens of a farsighted person behaves like a magnifying glass. Most hyperopia is in young people and they grow out of much of it. It also reappears in people past 40 as the natural lens loses focus. ...Read moreSee 1 more doctor answer
Yes: There are procedures for farsighted eyes and for nearsighted eyes as well. See an ophthalmologist to discuss your options. ...Read more
A little more: Polycarbonate lenses have a higher index of refraction and can be made a little thinner which lightens the eyeglasses and makes them more comfortable. So they charge a little more for them. I consider eyeglass costs way too high for the technology and manufacturing costs, but it is an industry charging what the public will put up with. ...Read more
LASIK: Typically yes. The majority of astigmatism can be corrected with refractive surgery. However, in patients with severe astigmatism or with irregular corneas inducing astigmatism, it is not recommended these patient undergo surgery. A detailed examination with an eye surgeon specializing in vision correction surgery such as LASIK/PRK is the best next step to determine if you are a good candidate. ...Read moreSee 1 more doctor answer
Depends : There are many approaches to provide better vision. Cataract surgery despite all the advantages and even with femto laser assisted cataract surgery still has a higher risk profile than lasik . However if you have visually significant cataracts then lasik a poor choice. ...Read moreSee 4 more doctor answers
Had cataract & astigmatism correction with iol lens but correction not sufficient for distance vision. Now prk is recommended. Good solution?
No difference: The risk is the same for each. ...Read more
