How does the eye doctor test for cataracts?

Visual inspection. Usually the eye doctor looks at the lens to determine the presence or absence of a cataract. He or she then determines whether or not the cataract is affecting your vision.
Slitlamp diated exam. The eyeMD can see a cataract at the microscope (slit lamp) especially when pt is dilated. Evaluating pt's vision, glare testing, and being sure all other layers of eye are normal, helps the MD determine if the cataract is the cause of the decreased vision.
Cataracts. An eye exam by an ophthalmologist will detect whether cataracts are present. The eye doctor will use the slit lamp to look at the eyes under magnification to detect cataracts.

Cataracts . Cataracts can affect a person's vision, resulting in blurred vision, and in some cases progressive myopia (as you report). Thankfully, a simple eye exam where your doctor would measure your vision can result in an accurate diagnosis of whether or not you have a cataract. If you have cataracts, there are now new intraocular lenses that can correct your vision, including the tecnis multifocal, restor, and crystalens - all which are designed to reduce your need for glasses after surgery. Toric intraocular lenses have also been designed for correcting astigmatism at the time of cataract surgery.

Cataracts . Cataracts are caused by a gradual clouding of the lens of the eye. Typically if the lens of the eye is cloudy, your vision will be cloudy, and glasses will not improve your vision. As the cataract gets thicker and darker, the power of the lens gets stronger, and you can get more near sighted. Your doctor will check you for glasses, and dilate your eye, and examine the cataract to see how cloudy it is. Based on the examination, you and your doctor can make an informed decision.

It . It is best to have cataract surgery when you feel your vision is not clear enough for your lifestyle. Poor vision for night driving, or difficulty reading fine print are common complaints. For most patients, a reduction of best corrected (with eyeglasses or contact lenses) vision to 20/40 or 20/50 is where patients start to notice their vision is impaired. This is the level of vision that many patients decide to have cataract surgery. Some patients do wait until their vision is worse than the 20/40 to 20/50 level. Read more...
The . The best way to determine if you should consider cataract surgery now is to ask yourself one simple question: am i happy with my current vision or is my sight getting to the point where it is hard for me to do my daily activities? If you're an airplane pilot, you will likely want cataract surgery when the cataracts are not too severe. You'd rather have an early cataract surgery than crash the plane. If you drive a lot, you will likely want to have cataract surgery before you fail the vision screening for your driver's license. If you spend the whole day gardening and you don't drive, you may be happy with 20/60 vision and then there's no rush to do cataract surgery. In the old days, with the older techniques of surgery, there was a higher risk of complications. For this reason, eye surgeons waited until cataracts were quite severe, often to the point of legal blindness so that no matter what happened during surgery, the patients would be happy. If you start with 20/200 vision and the old style cataract surgery (which used to be done with scissors, stitches, etc) gave you 20/80 vision, then you would be happy. This is when the saying "wait until it's ripe" came from. Waiting until a cataract is "ripe" does not make any sense for modern day, new techniques of cataract surgery. Today cataract surgery can be done with no needles, no bleeding, no stitches, no pain, no eye patch, and in 10 minutes or so. Typical patients should be able to recover excellent vision, enough to pass the driving test, the day after cataract surgery. Discuss your options with your eye surgeon. If you're happy with your vision, do nothing. If you'd like to see better, then consider cataract surgery.
