Timolol and postoperative intraocular pressure.

T Tomoda, A W Tuberville, T O Wood

    Journal - American Intra-Ocular Implant Society
    |January 1, 1984
    PubMed
    Summary

    Timolol eye drops did not prevent a temporary rise in intraocular pressure (IOP) after cataract surgery. Postoperative IOP returned to normal within three days for all patients, regardless of timolol use.

    Area of Science:

    • Ophthalmology
    • Surgical Outcomes
    • Pharmacology

    Background:

    • Acute postoperative intraocular pressure (IOP) elevation is a common concern following cataract surgery.
    • Extracapsular cataract extraction (ECCE) with posterior chamber lens implantation is a standard surgical procedure.

    Purpose of the Study:

    • To investigate the efficacy of topical timolol in mitigating acute postoperative IOP spikes after ECCE.
    • To evaluate the impact of immediate postoperative timolol instillation on IOP trends during the first week.

    Main Methods:

    • A prospective study involving 85 eyes undergoing ECCE and posterior chamber lens implantation.
    • Eyes were randomized into two groups: one receiving immediate postoperative timolol instillation (34 eyes), and a control group (51 eyes).
    • Intraocular pressure (IOP) was monitored daily for seven days post-surgery.

    Main Results:

    • No significant difference in mean IOP was observed between the timolol and control groups on postoperative day one.
    • A similar percentage of patients in both groups experienced transient ocular hypertension (IOP > 23.0 mm Hg).
    • IOP normalized within three days for all patients, irrespective of timolol treatment.

    Conclusions:

    • Timolol instillation immediately after ECCE and posterior chamber lens implantation does not effectively reduce acute postoperative IOP elevation.
    • The study suggests that timolol is not beneficial for managing transient IOP spikes in this surgical context.
