Aim: The aim of the study was to assess the effect of intracameral preservative-free lignocaine (1%) on the dilatation of pupil while doing phacoemulsification surgery. Materials and Methods: A prospective study carried out on 21 patients in a tertiary care hospital. The pupil diameter was measured just before instilling intracameral preservative-free lignocaine, after 1 min and 5 min, respectively. Any mydriatic was not used either before or during the surgery. Effects were compared between male and female patients and between light- and dark-colored irides patients. Results: The diameter of pupil after instillation of intracameral lignocaine was significantly higher. The effect was more pronounced in light-colored irides. There was no difference in the pupillary diameter between both the sexes. Conclusion: Intracameral preservative-free 1% lignocaine has a fast and effective mydriatic property and with more studies, can be used as a safe alternative to topical and intracameral mydriatic while phacoemulsification.

The authors here describe manual small incision cataract surgery (MSICS) by using topical anesthesia with intracameral 0.5% lignocaine, which eliminates the hazards of local anesthesia, cuts down cost and time taken for the administration of local anesthesia. Aims: To evaluate the patients′ and surgeons′ experience in MSICS using topical anesthesia with intracameral lignocaine in terms of pain, surgical complications, and outcome. Settings and Design: Prospective interventional case series. Materials and Methods: Ninety-six patients of senile cataract were operated by MSICS under topical anesthesia with intracameral lignocaine using "fish hook technique." The patients and the single operating surgeon were given a questionnaire to evaluate their experience in terms of pain, surgical experience, and complications. Statistical Analysis Used: Statistical analysis software "Analyseit." Results: There were 96 patients enrolled in the study. The mean pain score was 0.7 (SD ± 0.97, range 0-5, median 0.0, and mode 0.0). Fifty-one patients (53%) had pain score of zero, that is, no pain. Ninety-one patients (~95%) had a score of less than 3, that is, mild pain to none. All the surgeries were complication-free except one and the surgeon′s experience was favorable in terms of patient′s cooperation, anterior chamber stability, difficulty, and complications. The ocular movements were not affected, and hence, the eye patch could be removed immediately following the surgery. Conclusions: MSICS can be performed under topical anesthesia with intracameral lignocaine, which makes the surgery patient friendly, without compromising the outcome.
