Acorn laser cataract surgery information

The opening in the capsule can be controlled by the laser down to a tenth of a millimeter. The laser consistently generates an opening of the desired diameter and a shape that is difficult to reproduce manually. An experienced laser surgeon will make a fully accurate opening. Sometimes the shape may be eccentric or oval.

A more circular, central and precise opening is best when implanting an artificial lens. When using the Restor and Tecnis brands, the openings are usually a tad smaller than for Crystalens.

Laser surgery for cataracts is equally helpful in wound management. A precise opening will allow entry and exit of instruments and insertion of the implant without undue stress on the wound. This prevents wound leakage at the end of the procedure and therefore faster healing.

Splitting of the lens by laser is done without any stress on the capsular bag or the zonular support system. Energy from the laser is delivered from the bottom towards the top, which allows gas generated by conversion of the lens material into plasma to escape, as well as allow the subsequent beam to work without interference from gas bubbles.

Sound energy, a commonly used procedure, can cause inflammation and affect the functioning of the cornea.

In dense cataracts, the bottom is difficult to perceive so the capsule can be accidentally ruptured. Real-time display with the ability to be precise and avoid the bottom of the bag becomes an advantage when using the laser for cataract procedures. Breaking apart a hard, afflicted lens can be time-consuming with traditional sound wave technology. Lasers decrease the time and energy required to accomplish the same task.

Further progress in laser technology is coming. One day maybe even robots will be able to do safe and effective cataract surgeries. For now, we must still rely upon the skilled hands of human surgeons.

Am I too old to have Prelex?

A wonderful lady from connecticut around 80 years of age (a woman never tells her age, she reminded us) asked whether she was too old to have Prelex. Prelex, as you may recall is an influential new vision correction procedure that concerns replacing the eyes normal lens using a presbyopic implant lens. This procedure is perfect for patients forty five and above and it can significantly improve vision and allow one to obtain quality vision for rest of their life. People younger than 45 have significant flexibility in their natural lens which allows them to continuously change the focussing power of their eye naturally. Since people older than 45 to 50 have already lost much of the flexibility in their natural lens, there is a loss of natural focusing flexibility.
This ability is regained in a Presbyopic refractive lens exchange procedure or Prelex.
You are never too young to fall in love(quote from Mother Teresa) or too old to have Prelex(Quote from the author of the book on Prelex). Here is a video of a 89 year old young man- why I love Prelex.
A refractive lens exchange is not generally recommended for people under 45, unless the diagnosis and careful testing reveals it to be the best option. The procedure is proving popular all over globe including India and Nigeria.
The experience of a new book termed Prelex enables millions of individuals the access to quality perspective, care, facts. In this prelex book readers can learn in regards to the prelex procedure.
The prelex process involves changing the eyes natural lens for just a presbyopic implant lens. There is a range of implant lenses from which to choose including; Restor, Crystalens, and Tecnis implants. Each lens deviates in potential and performance. A beneficial surgeon can discuss the advantages and disadvantages of every single lens and together you may choose the best option for your lifestyle.
So this nice lady is visiting her daughter in maryland, to discuss having her prelex procedure.
