The meeting concluded with a video presented by Dr Buratto showing a case where the laser’s OCT imaging erroneously read the anterior cornea and capsule surfaces, resulting in the treatments being delivered too posteriorly. After recognising that the capsulotomy was made inside the nucleus, Dr Buratto suspended the laser procedure and, therefore, avoided misplacement of the laser lens treatment into the vitreous cavity.
The experience served as a reminder that while the laser avoids certain sources of human error and automates multiple steps of cataract surgery, users must still pay careful attention to what the laser will be doing.
“The precision benefits of the laser make surgeons very trusting of its performance. However, surgeons must be mindful to not flash quickly through all of the screens, assuming that the OCT pick-up of the lens capsule position is always correct,” said Dr Bruce Allan, Moorfields Eye Hospital.
“There is still a need to carefully review all of the information before pressing the button to proceed. Laser manufacturers can help surgeons at this stage by flashing up warnings where lens dimensions are measured outside two standard deviations from population mean figures.”
