This study suggests a role of TSDLC as an effective, safe, and rapid method of treatment in patients with good vision over a 24-month period. The loss of VA in some patients is similar to previously reported studies in patients having cyclodiode, trabeculectomy, or tube surgery.

Goldmann applanation tonometers are not as accurate as the manufacturer's recommended calibration error tolerance of +/-0.5 mm Hg would suggest. Calibration error of less than +/-2.5 mm Hg is clinically acceptable. Calibration error checks should be carried out once monthly and tonometers with calibration error greater than +/-2.5 mm Hg returned to the manufacturer for re-calibration. Additional checks should be made if tonometers suffer specific damage. Ideally individual ophthalmologists should check calibration before each session.

In this small series of patients with late-onset retinal degeneration, cataract surgery was successfully performed without long-term complications involving intraocular lens stability. The objective improvement in CDVA seemed to be limited to patients with good foveal photoreceptor architecture.
