How is the Laserphaco probe used? The Laserphaco Probe uses a system of lasers, suction, and irrigation to remove the affected lens & replace it with an artificial lens that won't deteriorate over time. This combination of technology provides a non-invasive, as well as an almost-permanent, solution to cataracts.
How much did the laserphaco probe cost in the past?
In 1981, Bath conceived of the invention for which she has become famous – the Laserphaco Probe, a surgical tool that uses a laser to vaporize cataracts via a tiny, 1-millimeter insertion into a patient’s eye. After using the Laserphaco Probe to remove a cataract, the patient’s lens can be removed and a replacement lens inserted.
What was the purpose of the laserphaco?

What are some characteristics of a probe?
the individual sensor flow characteristics. probe must pass through a wall to reach the point of measurement. The simplest shape of wall penetration is a small, circular hole. It is therefore desirable, in many applica- tions, that the probe support be of a circular cross section and that the sensing head com-

How is the laserphaco used today?
In fact, the laserphaco probe is still used to treat cataracts today. Dr. Bath also founded the American Institute for the Prevention of Blindness in Washington, D.C., a non-profit advocacy organization.
How did the Laserphaco Probe change the world?
Bath was the first African American woman doctor to patent a medical device, the Laserphaco Probe for the treatment of cataracts, which has helped restore or improve vision to millions of patients worldwide—making it one of the most important developments in the field of ophthalmology.
Why did Patricia Bath invent the Laserphaco Probe?
Bath was also a laser scientist and inventor. Her interest, experience, and research on cataracts lead to her invention of a new device and method to remove cataracts—the laserphaco probe. When she first conceived of the device in 1981, her idea was more advanced than the technology available at the time.
Who discovered the Laserphaco Probe?
Patricia BathLaserphaco / InventorPatricia Bath was an ophthalmologist known for inventing the Laserphaco Probe, a tool used in cataract surgery. After obtaining a medical degree from Howard University, she attended Columbia University and was the first African American to complete an ophthalmology residency program (1973).
Who invented eye surgery?
Peyman (born 1 January 1937) is an ophthalmologist, retina surgeon, and inventor. He is best known for his invention of LASIK eye surgery, a vision correction procedure designed to allow people to see clearly without glasses.
What is something unique about the inventor of the Laserphaco Probe?
Inventing the Laserphaco Probe Harnessing laser technology, the device created a less painful and more precise treatment of cataracts. She received a patent for the device in 1988, becoming the first African American female doctor to receive a patent for a medical purpose.

What is laserphaco cataract surgery?
1986: Laser Ablation She invented the laserphaco probe, which used light energy to ablate and remove cataracts. This treatment was revolutionary and helped Dr. Bath restore vision in patients who had been blind for more than three decades.
Who invented cataract eye surgery?
The procedure is termed “extracapsular” because the lens capsule is left in place. The first true cataract extraction was performed in 1747, in Paris, by the French surgeon Jacques Daviel. His procedure was more effective than couching, with an overall success rate of 50%.
Did Patricia Bath invent laser eye surgery?

How do they fix cataracts?
During cataract surgery, the clouded lens is removed, and a clear artificial lens is usually implanted. In some cases, however, a cataract may be removed without implanting an artificial lens. Surgical methods used to remove cataracts include: Using an ultrasound probe to break up the lens for removal.
Incisions
Capsulotomy
Hydrodissection
- The most important technical change we believe we have made is that we are less exuberant with our initial hydrodissection. In the presence of a smaller, perfectly round capsulotomy, vigorous hydrodissection will at times cause the lens nucleus to vault forward, occluding the anterior capsule, creating a capsular block syndrome, pushing the fluid posteriorly, and possibly damagi…
Division of The Nucleus
- eyetube.net/?v=lufee. We used to create a central groove. Now, we sculpt the central doughnut we have created with the laser to create a hole in the center of the nucleus. In the past, we split and then chopped the lens with a standard chopper. We now employ a chopper with an arc that fits nicely into the doughnut hole created in the lens to increase the contact area between the lens a…
Cataract Extraction
- During standard phacoemulsification, we use peristaltic vacuum to hold the nuclei, which requires full occlusion of the tip. After the use of the femtosecond laser, we find that the quadrants are mostly free-floating. In our experience, the Venturi mode brings the lens nuclei to the center without the need for full occlusion, which makes quadrant r...
Cortical Cleanup
- One of the easier aspects of traditional cataract surgery, cortical cleanup is difficult after the use of the laser for two reasons. First, there are no free cortical edges to grab onto with the I/A handpiece. More importantly, the hydrodissection plane used to be located between the capsule and the cortex, cleaving the cortical material and making it easier to remove. During laser catara…
Conclusion
- We have changed every aspect of our phaco technique. In so doing, we find that we have increased the safety of laser cataract surgery, and we hope that the techniques we have described will make adopting laser cataract surgery easier for other surgeons. Eric D. Donnenfeld, MD, is a professor of ophthalmology at NYU and a trustee of Dartmouth Medical School in Hanover, Ne…
