ABSTRACT
AIM: To study the visual improvement and to correlate the effect of energy used and number of shots with post procedural IOP spike following Nd-YAG laser capsulotomy cases.
MATERIALS AND METHODS: A total of 36 patients presented with pseudophakia with PCO attending ophthalmology outpaient department at Rajah Muthiah medical college hospital during the period of October 2020 - December 2022 were included in the study. Patients with glaucoma, Uveitis, high myopia, posterior segment disorders will be excluded from the study. The patient will be subjected to visual acuity testing, detailed slit lamp examination, IOP measurement using Non-contact tonometer pre and post laser procedure and detailed fundus examination done and results were interpreted.
OBSERVATION: Among the total 36 participants, 31.4% belong to age group 56 to 65 years followed by 28.6% in the age group 66 to 75 years. 51.4% were males and 48.6% were females. Of the total participants 28.6% had visual acuity of 6/24 in the affected eye and 22.9% had visual acuity of 6/36 in the affected eye.one subject presented with visual acuity of hand movements (HM) only in the involved eye.The mean pre-operative intraocular pressure among the participants was 1.85±0.73. 45.7% had preoperative IOP of 13 to 16 mmHg and 34.3% had preoperative IOP of 8 to 12. The mean number of YAG shots among the participants was 1.96±0.81. 36.3% were provided with 5 to 8 YAG shots and 33.3% with 2 to 4.The mean IOP among the participants in the preop was 14.03±2.92. The mean IOP immediately after the intervention was 15.29±2.83.The mean IOP 20 mins after the intervention was 17.43±2.96.Our study shows that the change in mean IOP after ND YAG LASER administration was significant with P value of less than 0.05 and also our study shows improvement in post laser BCVA with significant P values
CONCLUSION: The study concluded that all patients had good visual recovery. The post laser IOP raise is minimal and transient. It varies with amount of laser energy used. Hence recommended to use minimum possible laser energy and must be followed up for raised intraocular pressure changes.
