“…Furthermore, the point of capsulotomy centration has been a topic of discussion, concerning the profile of multifocal diffractive IOLs. This profile demands an optimization of the IOL centration, eliciting the search for the best match of the eye's several reference points and lines, along with the pupil's paramount role; some recent studies have proposed different capsulotomy centration points other than the classical pupil center [17,18]. Also, postoperative changes to the capsular bag such as anterior capsular contraction and posterior capsular opacification vary depending on the IOL material and amount of anterior capsule overlap of the IOL's edge [17].…”

PurposeTo assess the role of femtosecond laser‐assisted capsulotomy centration in the long‐term intraocular positioning of a multifocal intraocular lens.DesignProspective comparative study.MethodsA total of 60 eyes of 30 patients underwent femtosecond laser‐assisted Refractive Lens Exchange (RLE). For every patient, capsulotomy centration was randomly performed according to pupil centre (PC) in one eye and first Purkinje reflex (FPR) in the other. The intraocular lens (IOL) positioning, visual acuities, spherical equivalent, internal aberrometry and quality of vision were assessed and compared at 3 years' follow‐up between groups (PC and FPR).ResultsIntraocular lens positioning showed a statistically significant difference between groups, with a closer centration to the visual axis in the FPR patients (p < 0.001). Internal aberrometry showed higher values in the PC capsulotomy centration group (p < 0.01).ConclusionsFPR centered capsulotomy is associated to a closer centration of the IOL to the visual axis.

Purpose: To assess the role of femtosecond laser-assisted capsulotomy centration in the long-term intraocular positioning of a multifocal intraocular lens. Design: Prospective comparative study. Methods: A total of 60 eyes of 30 patients underwent femtosecond laser–assisted Refractive Lens Exchange (RLE). For every patient, capsulotomy centration was randomly performed according to pupil centre (PC) in one eye and first Purkinje reflex (FPR) in the other. The intraocular lens (IOL) positioning, visual acuities, spherical equivalent, internal aberrometry and quality of vision were assessed and compared at 3 years’ follow-up between groups (PC and FPR). Results: Intraocular lens positioning showed a statistically significant difference between groups, with a closer centration to the visual axis in the FPR patients (p=<0.001). Internal aberrometry showed higher values in the PC capsulotomy centration group (p<0.01). Conclusions: First Purkinje reflex (FPR) centered capsulotomy is associated to a closer centration of the IOL to the visual axis.

“…With the rapid aging of the global population, the incidence of cataracts is increasing. According to incomplete statistics from the World Health Organization, there are about 500,000 new cataract blind people yearly [ 10 , 11 ]. Currently, the number of cataract blindness in China is second only to India, ranking second in the world.…”

Backgrounds. The eyeball and its ancillary tissues are important organs with the same shape and structure, and examining the surgical site is particularly important in ophthalmic surgery. A safe and easy-to-operate ophthalmic surgical hole towel is of great significance for improving the safety of ophthalmic surgery. Objective. To explore the effect of intelligent operating hole towel in cataract patients. Methods. From April 2020 to April 2021, 1220 cases of cataract patients who needed surgery in the second affiliated hospital Zhejiang University college of medicine, were recruited and randomly divided into the control group and the observation group. The control group adopted a disposable ophthalmic single-port operation cloth, and the intelligent surgical hole towel was used in the observation group. Incidences of surgical site errors, the amount of operation time, bacterial infections, and patient satisfaction were recorded. Results. The average operation time in the observation group had obviously reduced compared with the control group p < 0.05 . Moreover, patients’ overall medical satisfaction in the observation group improved significantly compared with the control group p < 0.05 . Conclusions. The design and use of the new intelligent ophthalmic surgical hole towel can promote the efficiency of ophthalmic surgery, realize the intelligent verification of surgical eye, reduce the risk of surgical site errors and improve medical safety.
