Topical anesthetics have become relatively popular in recent years. Their use has minimized the risks of traditional anesthetics in ophthalmologic procedures and also reduce the invasiveness of the procedure.

The development of this type of anesthetic has been influenced by:

The use of phacoemulsification in cataract surgery.

The growing need of ophthalmologic patients, especially in the case of cataract surgery, as topical anesthetics minimize the discomforts following surgery, promote a rapid recovery of visual function, and do not cause inflammation. The use of topical anesthetics should also be accompanied by a fast and refined technique requiring an experienced surgeon and the patient’s cooperation.

Some very apprehensive patients or those with a tendency for anxiety are not good candidates for the use of topical anesthetics.

Possible Complications:

Toxicity of the anesthetic through excessive use.
Poor cooperation of the patient.
An inexperienced surgeon.


-Rigorous selection of the patient.
-In general, topical anesthetics are not used with high-risk patients, except in those where anti-coagulants are necessary. In these cases, a topical anesthetic is recommended.
-Have a sedative anesthesia available.
-The surgeon must master anesthetic alternatives
-Topical anesthesia is an excellent choice for a satisfactory level of performance, although the degree of analgesia is not as high as other forms of anesthesia.

The use of anesthetic eye drops in cataract surgery promotes almost immediate recovery of visual acuity, eliminates bleeding, edema, etc. and decreases the stress of the anesthesia on the patient.
