In Phase I, one of the three surgeons operated the LensX®, another performed the FLACS surgery (FLACS I) in one operating room (OR1), while the third surgeon performed the conventional phacoemulsification procedure (MANUAL) in another operating room (OR2). On subsequent days, the surgeons rotated between LensX®, FLACS and MANUAL surgery

Study of the Efficiency and Workflow of Femtosecond Laser Assisted Cataract Surgery in a Spanish Public Hospital

Surgical and roll-over times (measured in minutes) for both conventional phacoemulsification and FLACS were assessed: start time of patient preparation, anesthesia and surgery, surgery end time, time needed to transfer the patient to resting area, and time of discharge; time from the insertion of blepharostat to its removal after ending the surgical procedure, time from the moment the patient entered the OR to the moment the patient left the OR after finishing the surgery, and time from the admission of the patient to the surgical area to the discharge once the intervention was finished.

Likewise, mean phacoemulsification energy values (measured in %, as provided bu the phacoemulsification device) used in each procedure was also recorded (CDE: cumulative dissipated energy).

Intraoperative complications were also recorded, including loss of suction, loss of fixation/follow-up and incomplete capsulorrhexis for the femtosecond laser-assisted stage, and incomplete rexis, capsular rupture, IOL dislocation and incisions without coaptation for the phacoemulsification stage.

Study design. This study was composed of two phases and was carried out by three consultant surgeons. No resident or trainee was involved in the performance of the surgeries. In Phase I, one of the three surgeons operated the LensX®, another performed the FLACS surgery (FLACS I) in one operating room (OR1), while the third surgeon performed the conventional phacoemulsification procedure (MANUAL) in another operating room (OR2). On subsequent days, the surgeons rotated between LensX®, FLACS and MANUAL surgery (Figure 1). All the settings for the Infiniti® and the LensX® were the same for all surgeons (see below). The cataracts included in the FLACS I group were presumably straightforward, as they were part of the learning curve for the surgeons and were evaluated by consultant ophthalmologists (it must be considered that the maximum best-corrected visual acuity [BCVA] for being eligible for cataract surgery in the Andalusian public System is 0.4 logMAR).

Patients with known keratoconus or pellucid marginal degeneration will be invited to join the study. The study is partly a continuation in the management of patients who have had previous keratophakia, who will have near-normal or supra-physiological levels of corneal thickness. It is also intended for patients with relatively mild keratoconus who have sufficient corneal thickness to allow a limited laser ablation whilst still leaving a residual stromal bed of at least 350μ.

Pellucid Marginal Degeneration

Surgery is performed with topical anaesthesia. The central corneal epithelium is removed. Excimer laser ablation is applied (typically 15-30 seconds). Residual bed thickness is checked with an ultrasonic pachymeter. Topical application of riboflavin 0.1% in dextran is commenced at 5 minute intervals. When an adequate saturation of the anterior chamber with riboflavin has been achieved, cross-linking treatment will proceed. Output from the UV light generating equipment is measured with a UV light meter and set at 3mW/cm². Thirty minutes of treatment is given, interrupted at five minute intervals by the application of more topical riboflavin drops. Finally the eye has a bandage soft contact lens placed, with preservative free topical antibiotic, steroid, and cycloplegic drop application.
