Description

Technical Field

[0001] This invention relates to the field of ophthalmic instrument technology, and more particularly to an ophthalmic instrument for correcting entropion and trichiasis. Background Technology

[0002] Entropion, or eyelid eversion, is an abnormal eyelid position where the eyelid margin curls inwards towards the eyeball, causing the eyelashes to turn inwards towards the surface of the eye. Trichiasis, or eyelashes growing in the opposite direction, causes eyelashes to grow in the opposite direction, frequently rubbing against the cornea and conjunctiva. Both conditions can cause discomfort such as a foreign body sensation, pain, tearing, and photophobia. If left uncorrected, they can lead to corneal epithelial damage, infection, ulceration, and even vision impairment. Therefore, specialized corrective instruments are needed to assist the operator in precise manipulation to restore the normal eyelid position and eyelash growth direction, reducing patient suffering and protecting eye health.

[0003] Existing technologies for correcting entropion and trichiasis have several shortcomings: 1. Traditional instruments have fixed or limited angles in their eyelid clamping structures, making it difficult to adapt to the different eyelid flexion angles required by different patients. Furthermore, the contact position with the eyelid is inconvenient to adjust, and it is impossible to stably fix the eyelid in different locations, causing great inconvenience to the operator. 2. The height adjustment precision of the instruments is insufficient, making it difficult to adapt to individual differences in the vertical distance between the eyes of different patients. This results in poor fit between the instrument and the eye, affecting the corrective effect and ease of operation, and has low compatibility. Summary of the Invention
