From there, the hospital grew steadily due to increases in the need for ophthalmologic treatment. It began building wards so that patients could be accompanied by relatives, which was especially important for patients who traveled from afar, added extra beds, and bought an X-ray unit. By 1930, 14 wards were built for patients. In addition to physical size, the hospital also grew in the professional context. It developed a training program for male nurses in 1926 and for dispensers in 1931. In May 1935, however, an earthquake hit Quetta and destroyed the hospital. He returned to England to raise money for the Rebuilding Fund for the hospital. In the meantime, temporary structures were used. The reconstruction of the hospital began in 1936 and was finally completed on 6 May 1940. In 1909, a wealthy Hindu philanthropist invited Holland to treat patients in Shikarpur, in North Sind. Holland agreed to treat the patients for free if the philanthropist would use the money to build a hospital. In only one year, this hospital grew to be one of the largest eye clinics in the world, treating up to 600 patients at a time. The success of this hospital became widespread. Soon, eye specialists all around the world from India to the United States came to the hospital to learn more through both observation and working. With the additional help, about 3,000 operations (1,400 for cataracts) were performed at the hospital during the two months it was open for each year. It was recorded that just Holland himself performed up to 70 cataract operations a day. Since the Shikarpur hospital's establishment, over 150,000 eye operations have been performed, including 77, 600 successful cataract extractions. Another clinic was later established in the nearby city of Khairpur, which was also in North Sind. In addition to the establishment of many successful hospital, Holland contributed to ophthalmology in his research and development of surgical procedures. For example, Holland discovered that iridectomy and iridotomy were more effective than drainage procedures in the treatment of closed-angle glaucoma. He also found that an iridectomy could help with the high intraocular pressures of a cataract patient and defer cataract surgery. Moreover, Holland's specific iridectomy and iridotomy methods were able to remove the danger of the iris prolapsing and, thus, simplify and improve postoperative treatment. This included allowing movement after surgery and being able to eat a normal diet as opposed to a liquid diet, both of which contributed to the patient's wellbeing in the recovery process.
