abovementioned. Accordingly, our Directors are of the view that, it is expected that the downward fluctuations, if any, in number of SMILE surgeries conducted should stabilize gradually and will not have material adverse impact on our Group’s operation and financial performance.

Revenue generated from treatment for other eye problems had increased during the Track Record Period, from approximately HK\$36.3 million for the year ended 31 March 2019 to approximately HK\$36.8 million which for the year ended 31 March 2020 which was generally consistent with an increase in total number of patient visits, and then further increased to HK\$44.8 million for the year ended 31 March 2021 which was mainly due to the increase in revenue recorded for our standard cataract surgeries and laser procedures. Revenue generated from treatment for other eye problems had increased during the Track Record Period, from approximately HK\$12.3 million for the four months ended 31 July 2020 to approximately HK\$22.1 million for the four months ended 31 July 2021, which was mainly due to the increase in revenue recorded for each of our standard cataract surgeries, laser procedures, PPV surgeries and other treatments/surgeries. As the majority of our Medical Practitioners had been providing ophthalmic services under our brand ‘‘Clarity’’ for more than three years, we were able to build up our patient base by word-of-mouth referrals from existing patients and as a result, our Directors are of the view that it had contributed to the increase in revenue generated from treatments for other eye problems during the four months ended 31 July 2021.

Revenue generated from our consultation and examination service decreased from approximately HK\$9.2 million for the year ended 31 March 2019 to HK\$8.5 million for the year ended 31 March 2020 and had subsequently increased to HK\$9.1 million for the year ended 31 March 2021. Revenue generated from the sales of prescription remained relatively stable during the Track Record Period, which amounted to approximately HK\$6.3 million, HK\$6.2 million and HK\$6.9 million, respectively. Revenue generated from our consultation and examination service increased from approximately HK\$2.7 million for the four months ended 31 July 2020 to HK\$3.8 million for the four months ended 31 July 2021 which was mainly due to the growth of member of patient visits. Revenue generated from the sales of prescription increased by approximately HK\$0.8 million, or 39.4%, from approximately HK\$2.0 million for the four months ended 31 July 2020 to HK\$2.8 million for the four months ended 31 July 2021. The increase in revenue generated from sales of prescriptions and others was generally in line with our overall increase in consultation and examination services provided during the period.

# Consultation and Examination Services

We provide medical consultation and examination services to our patients through our Medical Practitioners and optometrists, with support from our registered and enrolled nurses and/or nursing staff. Consultation and examination services mainly include assessments on eye conditions, such as visual acuity, refraction, anterior segment examination, fundal examination and intraocular pressure measurement. After the completion of consultation, examination and diagnosis based on our patients’ specific conditions, needs and concerns, Medication may be prescribed and/or treatments may be recommended to the patients by our Medical Practitioners. Follow-up consultation and examination services may be provided depending on the condition of the patients after taking the recommended Medication and/or completion of treatment.

# Treatment Services

We provide a range of ophthalmic treatments at our Surgery Centres or in the Private Hospitals, depending on the complexity of the treatment, the need of general anaesthesia and/or the choice of our patients. Treatment services may be recommended to our patients after the diagnosis through consultation and examination, taking into consideration a number of factors, in particular, the age and condition of the patient, the safety, effectiveness, risks and possible side-effects of the relevant treatment. One or more types of treatments may be recommended, depending on patients’ eye problems. Our Medical Practitioners will explain to patients the associated benefits and potential risks of each recommended treatment and any alternative treatment choices. We record the details of patients’ drug allergy information into our Medical Centre Management System and arrange relevant checks to ascertain the degree of myopia or hyperopia, or the curvature of corneas, before the provision of treatment services. All our patients are required to sign an operation consent form in the presence of the responsible Medical Practitioner and at least one nursing staff. Our treatment services are performed by our Medical Practitioners with assistance from frontline staff.
