Summary
Refractive surgery can cause binocular vision and accommodation issues, with reduced fusional vergence being common. Preoperative assessments are crucial to identify risks and prevent postoperative visual complaints.
Area of Science:
- Ophthalmology
- Optometry
- Vision Science
Background:
- Refractive surgery aims to correct vision but can impact binocular function and accommodation.
- Preoperative assessment of binocular vision and accommodation is vital for successful outcomes.
Purpose of the Study:
- To review binocular and accommodative disorders after refractive surgery in healthy patients.
- To identify risk factors for postoperative visual complaints.
Main Methods:
- Bibliographic revision of studies published before July 1, 2017.
- Included papers assessing accommodation and/or binocularity post-refractive surgery.
- PubMed search yielded 1273 papers; 95 met inclusion criteria.
Main Results:
- Few studies reported binocular vision or accommodative changes post-refractive surgery.
- Reduced fusional vergence was the most frequent alteration.
- Anisometropia is a significant risk factor for binocular complaints; many diplopia cases were misdiagnosed preoperative issues.
Conclusions:
- Comprehensive preoperative binocular and accommodation assessment is essential.
- Measuring parameters like phoric posture and fusional reserves can identify risks.
- Early identification of risk factors improves refractive surgery success and reduces symptoms.

Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

In statistics, several tools are used to interpret the data. Measures of central tendency represent the characteristics of the data, such as mean, median, and mode. Additionally, measures of variance like standard deviation and range are used to find the spread of data from the mean. Relative standing measures the distance between data locations. Commonly used measures of relative standings are percentile, z score, and quartiles.

Data are individual items of information obtained from a population or sample. Data may be classified as qualitative (categorical), quantitative continuous, or quantitative discrete. Because it is not practical to measure the entire population in a study, researchers use samples to represent the population. A random sample is a representative group from the population chosen by using a method that gives each individual in the population an equal chance of being included in the sample. Random...

Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
