Photokeratitis/Photochemical Injury: This condition is caused by exposure to ultraviolet radiation, such as from a laser. It leads to damage to the corneal epithelium, resulting in pain, blurred vision, and sensitivity to light. The symptoms typically resolve within 48 hours.

Corneal Abrasion: Direct injury from the laser or subsequent rubbing of the eye could cause a corneal abrasion, leading to pain, blurred vision, and redness.
Uveitis: Inflammation of the uvea, which could be triggered by the laser exposure, causing pain, blurred vision, and sensitivity to light.
Vitreous Floaters: The intense light from the laser might cause the perception of new or increased vitreous floaters, although this would not typically cause pain.

Retinal Damage/Burn: Direct laser exposure can cause a retinal burn, leading to severe and potentially permanent vision loss. Prompt diagnosis and treatment are crucial.
Macular Edema: Swelling of the macula due to laser exposure, which could result in significant vision loss if not promptly addressed.
Optic Neuritis: Inflammation of the optic nerve, which could be triggered by the laser and lead to severe vision loss.

Solar Retinopathy: Although more commonly associated with viewing a solar eclipse without proper eye protection, any intense light exposure, including from a laser, could potentially cause this condition, leading to serious vision impairment.
Ocular Migraine: Some individuals might experience an ocular migraine triggered by the intense light, leading to transient visual disturbances, including blurred vision and pain.
