Design outcomes

Primary

Measure	Time frame
Primary anatomical success rate is defined as the retina maintaining reattached after one operation at 12 months.	—

Secondary

Measure	Time frame
1. Best corrected visual acuity (BCVA) is measured using ETDRS chart converted to the logarithm of the minimum angle of resolution (logMAR) at 12 months 2. Cataract progression is determined by one doctor if considered to be visually significant at 12 months 3. Intraocular pressure (IOP) measured using a non-contact tonometer at one day, one week, one month, three months, six months and 12 months 4. Choroidal thickness (CT) is measured using enhanced depth-imaging spectral-domain optical coherence tomography (SD-OCT) imaging at subfovea (Spectralis; Heidelberg Engineering, Heidelberg, Germany) at one day, one week, one month, three months, six months and 12 months 5. Axial length (AL) is measured using the IOL Master (Carl Zeiss, Tubingen, Germany) at one month, three months, six months and 12 months 6. Complications is measured using slitlamp at one day, one week, one month, three months, six months and 12 months	—
