Techniques for Cataract Surgery

It is not always likely that surgery of two different people who are diagnosed with cataract are same. The techniques varry with the patient and the size of the cataract. There are three basic techniques for cataract surgery:

Phacoemulsification: This is the most common form of cataract removal. In this most modern method, cataract surgery can usually be performed in less than 30 minutes and usually requires only minimal sedation. Numbing eyedrops or an injection around the eye is used and, in general, no stitches are used to close the wound, and often no eye patch is required after surgery.

Extracapsular Cataract Surgery: This procedure is used mainly for very advanced cataracts in which the lens is too dense to dissolve into fragments. This technique requires a larger incision so that the cataract can be removed in one piece without being fragmented inside the eye. An artificial lens is placed in the same capsular bag.

Intracapsular Cataract Surgery: This surgical technique requires an even larger wound than extracapsular surgery, and the surgeon removes the entire lens and the surrounding capsule together. This technique requires the intraocular lens to be placed in a different location, in front of the iris. This method is rarely used today but can still be useful in certain situations.

Snow Blindness‬ and it's symptoms

‎Snow Blindness‬ can be identified by observing various symptoms
like eye pain, red eyes, a gritty feeling or sensation that something is "in" the eye, sensitivity to light, watery eyes, blurry vision, swollen eyes and/or eyelids, headaches, glare and halos around lights.
Vision loss from Snow Blindness is temporary and is normally restored within 24 to 48 hours. Though Snow Blindness doesn't cause actual blindness, vision can be significantly impaired for a short duration, making it unsafe to drive. Color vision also may be affected temporarily while you are ‪SnowBlind‬.

Don't Let Snow Blindness make your snowy trip a painful memory

Snow Blindness‬ is a painful, temporary loss of vision due to overexposure to the sun's UV rays. The medical term for snow blindness is ‪Photo Keratitis‬. Snow Blindness can, and often does occur in the absence of snow, as water and white sand are also highly reflective of the sun's UV rays and increase the risk of Snow Blindness.
The terms "‪Snow blind‬" and "Snow Blindness" are widely used because snow is highly reflective of Ultra Violet‬ radiation, as it can reflect more than 80 percent of the UV rays that falls upon it. Also, Skiing‬, ‪Mountain Climbing‬ and ‪Snowboarding‬ usually take place at relatively high altitudes, where the sun's UV rays are stronger. Combined, these factors can double your risk of getting ‪Sunburned Eyes‬, compared with being outdoors at lower altitudes in the summertime.

So, the next time when on a trip to a snow covered hill station, prevent Snow Blindness, wear sunglasses with a close-fitting, wrap-style frame or snow goggles. Make sure the lenses block 100 percent of UV rays.
