Aceclidine ophthalmic solution offers a pharmacological option for improving near vision in adults with presbyopia, but clarifying its indications and key precautions before and after administration is essential for safe and effective use.
I. Clear Indications
1. Target Population: Adult Patients with Presbyopia
(1) Aceclidine ophthalmic solution is approved for the treatment of presbyopia in adults.
(2) Presbyopia results from the age‑related decline in crystalline lens accommodation, typically beginning after age 40 with difficulty in near reading.
(3) This product improves uncorrected or corrected near vision by inducing miosis, which creates a “pinhole effect” that increases depth of field. It does not replace reading glasses but serves as an adjunctive, on‑demand daytime option.
2. Scope Includes Refractive Status
Simple presbyopia within the refractive range can be considered for use, provided the above refractive conditions are met.
3. Not for Use in Children or Adolescents
Since presbyopia is not a physiological phenomenon in this age group, this product has no paediatric indication. If individuals under 18 years present with similar visual complaints, refractive errors, accommodative spasm, or organic ocular diseases should be investigated; this medication should not be used.
II. Key Pre‑treatment Assessment and Preparation
1. Mandatory Comprehensive Ophthalmic Baseline Examination
A thorough eye examination by an ophthalmologist is required before use. This evaluation helps identify potential risk factors and provides a basis for treatment decisions.
2. History Taking and Allergy Inquiry
(1) The physician should carefully inquire about: ① history of iritis (anterior uveitis); ② history of retinal detachment, diabetic retinopathy, or maculopathy; ③ history of allergy to miotics, aceclidine, or any excipient of this product.
(2) In the presence of any of these conditions, the benefit‑risk ratio must be carefully assessed.
3. Pre‑operation for Contact Lens Wearers
(1) For those who habitually wear soft or rigid contact lenses, it should be clearly stated: remove the lenses before instillation, and wait at least 10 minutes after instillation before reinserting them.
(2) It is advisable to complete the instillation in the morning, allowing sufficient time for the solution to be absorbed before wearing the lenses, so as to avoid the viscous matrix affecting lens cleanliness and comfort.
III. Core Precautions During Administration
1. Strictly Follow the Two‑Drop, Two‑Step Method
(1) Instil one drop into each eye, wait 2 minutes, then instil the second drop.
(2) This interval reduces drug loss due to tear washout, ensuring that the active ingredient adequately contacts the iris sphincter.
(3) Do not instil the two drops consecutively without pause; otherwise, the first drop will be washed away by the second before it can adhere, compromising efficacy.
2. Visual Changes After Administration and How to Manage Them
(1) Transient dimming of vision or difficulty in switching focus between near and far may occur after instillation.
(2) This is due to miosis reducing the amount of light entering the eye, and the accommodative system needing time to readjust.
(3) During this period: ① avoid driving or operating precision machinery until vision is clear; ② exercise extra caution when going out at night or in low‑light conditions, and consider wearing light‑tinted sunglasses to reduce glare; ③ if prolonged reading is needed, supplement with additional lighting.
3. Watch for Sudden Visual Symptoms
(1) If during use you suddenly experience flashes of light, a sudden increase in floaters (many more than usual), visual field defects, or a “curtain”‑like shadow, seek immediate ophthalmic emergency care.
(2) These may be prodromal signs of retinal tears or detachment; although rare, early intervention is crucial for visual function preservation.
(3) Do not wait for a routine follow‑up or self‑observation.
4. Interval Requirements with Other Ophthalmic Drugs
(1) If using artificial tears, anti‑glaucoma, or anti‑allergy eye drops concurrently, allow at least 5 minutes between instillations.
(2) It is recommended to instil the more irritating or deeply penetrating drug (e.g., this product) first, followed by lubricating formulations.
(3) Insufficient intervals may cause dilution of the drugs and impair their respective efficacy.
