Transzonular moxifloxacin and dexamethasone delivery in phacoemulsification: A novel dropless regimen

To assess the safety and efficacy of transzonular moxifloxacin and dexamethasone versus standard postoperative topical drug regimen in phacoemulsification.

Nonrandomized prospective study.

The study included 100 eyes of 100 age and gender-matched individuals with senile cataract undergoing routine phacoemulsification. The patients were consecutively divided into transzonular (TZ = 50) and topical (TP = 50) groups. Both the groups were followed up for 4 weeks and assessed for intraocular inflammation, visual acuity, changes in intraocular pressure (IOP), and any adverse events.

The grades of inflammation were significantly lower in TZ as compared to the TP group ( P < 0.001). The IOP remained normal and comparable in both the groups. Most of the patients in the two groups attained a visual acuity of 0.2 or better at the end of the follow-up. No adverse effects and increased rate of endophthalmitis were noted in TZ group.

A one-time peroperative TZ moxifloxacin and dexamethasone combination is a safe and effective method to control postoperative inflammation after cataract surgery. A word of caution though, due precautions to be exercised to prevent the risk of inflammation and endophthalmitis.
