Which part of the eye is most at risk of damage from Nd:YAG and diode lasers?

The retina is the part of the eye that is most at risk of damage from Nd:YAG and diode lasers due to its sensitivity to light and its critical role in vision. These lasers emit high-energy light that can cause photochemical and thermal injury to retinal cells. The retina's structure is comprised of light-sensitive photoreceptor cells that can be harmed by excessive exposure to intense laser light, leading to potential vision loss or damage.

When using Nd:YAG and diode lasers, care must be taken to avoid direct exposure to the retina, as even brief moments of exposure can produce irreversible effects. Additionally, these types of lasers are often used in various medical procedures, such as in retinal laser treatments, further emphasizing the need for appropriate safety measures to protect the retinal tissue during their application.

While the cornea and iris are important components of the eye, they generally have greater tolerance to laser exposure compared to the retina. The pupil serves primarily as an aperture that regulates light entry and is not a target for damage from lasers. Therefore, understanding the vulnerability of the retina to laser exposure is crucial in preventing ocular injuries during laser procedures.
