Introduction
The choice of eye drops for dry and irritated eyes depends on the underlying cause. If eye dryness is due to prolonged lack of sleep, polyvinyl alcohol eye drops may be used as directed by a physician to improve symptoms. If caused by dry eye syndrome, aescin and digitalis glycosides eye drops can be used to relieve symptoms. For dry eyes resulting from insufficient tear secretion after corneal refractive surgery, carbomer ophthalmic gel can be applied to alleviate dry eye symptoms.
Generally, the choice of eye drops for dry or irritated eyes depends on the underlying cause, which may include physiological factors, pathological conditions such as dry eye syndrome, or procedures like corneal refractive surgery. The details are as follows:
1. Physiological Factors
Prolonged熬夜, extended use of electronic devices, or reading under dim lighting can lead to eye fatigue and cause dryness and irritation. It is recommended to use, under medical guidance, topical medications such as polyvinyl alcohol eye drops, sodium hyaluronate eye drops, or hypromellose eye drops to increase ocular surface moisture and relieve discomfort.
2. Pathological Factors
a) Dry Eye Syndrome
Dry eye syndrome occurs when the glands responsible for tear production deteriorate, leading to insufficient tear secretion. Under a doctor's supervision, medications such as diquafosol sodium eye drops, polyethylene glycol eye drops, or escin and digitalis glycosides eye drops may be used to promote tear secretion and improve symptoms.
b) Corneal Refractive Surgery
After corneal refractive surgery, tear film instability often leads to inadequate tear secretion, resulting in dry and irritated eyes. It is advisable to use, under medical guidance, medications such as recombinant bovine basic fibroblast growth factor eye drops or carbomer eye gel to enhance ocular surface lubrication and alleviate dry eye symptoms.
Patients should undergo appropriate examinations at a hospital before starting any medication and follow medical advice when selecting treatments. Self-medication without professional guidance is not recommended, as it may adversely affect eye health.
