Abstract Details


Intracameral mydriatic solution can eliminate the disadvantages of repeated eye drop instillation regimen and provide adequate mydriasis for phacoemulsification. This study was undertaken to evaluate the role of intracameral solution (0.5% lignocaine + 0.001% epinephrine) in initiating and maintaining mydriasis during phacoemulsification


Kaushalya Devi Eye Institute, Chhattari Chauraha, Pilibhit, India


One hundred forty five patients underwent phacoemulsification under topical anaesthesia during which pupillary mydriasis was achieved by use of intracameral mydriatic solution only. Pupillary diameter was measured during surgery: measurements being made preoperatively, after one minute of injecting the mydriatic solution, after emulsification of nucleus and after completion of surgery. Paired t-test was used to compare means. Spearman correlation coefficient was used to study the effect of various parameters on mydriasis


The pupil size increased from 2.3 mm (range 2-3.5mm SD 0.32) to 7.5 mm (range 6.5-10.5 mm SD 1.02) in one minute after delivery of the mydriatic solution and was 8.5mm (range 6.0-9.5mm SD 0.20) at the end of surgery. Duration of surgery, grade of nucleus, ultrasound time had statistically insignificant effect on mydriasis.


Intracameral solution containing 0.5% lignocaine and 0.001% epinephrine provides rapid mydriasis which is adequate for safe phacoemulsification without use of preoperative mydriatic eye drops and is unaffected by other parameters
