Macular edema is a rare complication that can occur under the influence of light. Damage occurs as a result of focusing the light beam on the macula. A 23-year-old patient reported to the hospital due to a sudden reduction in visual acuity of the left eye after visual contact with a geodetic laser at work. After full diagnosis and treatment implementation after 3 weeks, vision improvement was achieved. The case report shows the harmful effects of laser techniques on human vision.

Congenital cataracts are lens opacities that are already present at birth or are developing in the first years of life. Treatment consists of the surgical removal of the lens. Bilateral cataract deeply impairs vision, preventing the development of physiological reflex fixation and causes the development of nystagmus about 3 months of age. This nystagmus persists even after the surgical removal of cataracts without allowing often >0,1 visual acuity despite adequate aperture correction. Intraocular lens implants in children under the age of 1 are subject to discussion. Presents the patient's current visual acuity, in which an artificial intraocular lens was not implanted after a congenital cataract removal, retinal detachment, high myopia, glaucoma and persistent nystagmus. The whole treatment and adaptation mechanisms of the patient allowed to obtain surprising visual acuity for near vision without additional eyeglass correction.
