The laser is a wonder in itself. Lasers have evolved in a mere 25 years into so many fields. Now in medicine, the laser can be pointed to a single cell to cure its many illnesses, or broadened to burn or cut. The advantages of lasers are beneficial to today's modern people. The surgical techniques are somewhat easy to perform by a trained doctor, the prices of lasers and materials are within a respectable range, and the cost of operation is drastically reduced since the patient does not use up the hospital's other resources.
Some disadvantages do come up from using lasers.
Some lasers that have an immediate cure on a certain disease may cause a hidden imperfection that may not be noticed right away but may appear later in a worse condition. According to Parks et al. Lasers may be advanced but there is still a lot to know about the amplified light. There are hundreds being used today and more being invented with the newer technologies of today. Photocoagulation of the affected tissue appears to be the most common laser treatment in this report but there are many more different ways offered today.
