“…In our study, 29 of 54 patients [23]. As a result of the high incidence of PCO in patients with previous PPV surgery, previous study has proposed that PCCC combined with phacoemulsification may be an alternative to prevent PCO in postvitrectomy eyes with cataract [24]. Previous studies have found capsulorhexis size and its central localization play important roles in PCO [25,26].…”

“…Additionally, loss of support of the vitreous body may affect the attachment between IOL edge and capsular bag, promoting rapid LEC proliferation and contributing to PCO [ 23 ].

Introduction To evaluate the incidence, severity, and risk factors of early-onset posterior capsule opacification (PCO) following uneventful phacoemulsification and intraocular lens (IOL) implantation. Methods Patients with cataracts who underwent phacoemulsification and IOL implantation surgery for 3 months from September 2019 to April 2020 were enrolled. All the subjects completed a comprehensive ocular examination. Retroillumination images of the posterior capsule were obtained using a slit lamp with imaging system, and PCO was graded by two ophthalmologists. Univariate and multivariate logistic regression analyses were performed to assess the risk factors for PCO. Results A total of 1039 subjects were enrolled, with mean age 66.68 ± 11.43 years and 42.06% were male. The incidence of early-onset PCO in the 3 months after cataract surgery was 29.93%, and PCO of grade 3 and grade 4 was present in 31 patients (2.98%). Patients with complicated cataract had a higher incidence of PCO than age-related cataract, especially for patients with previous pars plana vitrectomy (PPV) surgery ( P < 0.001). Moreover, the incidence of PCO increased with the deficiency of capsulorhexis–IOL overlap ( P < 0.001). Multivariate logistic regression also showed that previous PPV surgery (OR 2.664, P = 0.003) and incomplete capsulorhexis–IOL overlap were risk factors for PCO (180–360° overlap: OR 2.058, P < 0.001; < 180° overlap: OR 5.403, P < 0.001). Conclusions Larger capsulorhexis and PPV surgery history contribute to the occurrence of early-onset PCO, indicating that primary posterior continuous curvilinear capsulorhexis can be considered during cataract surgery for patients with PPV history.

“…Nowadays, PPCCC is widely used in paediatric cataract surgery in the hope of preventing PCO, but not routinely adopted in adult cataract surgery, attributing to concerns regarding associated complications, including vitreous interface damage, vitreous prolapse, resulting cystoid macular oedema, and even retinal detachment. Published studies have demonstrated the safety and efficacy of PPCCC in age-related cataract [ 34 – 36 ]. In our study, PPCCC had no effect on the patient's subjective perception.…”

Introduction. Simultaneous Bilateral Cataract Surgery (SBCS) is still a relatively controversial procedure. The main objection is the risk of bilateral endophthalmitis or bilateral refractive error. However, SBCS has also some advantages (faster visual rehabilitation, lower risk of nosocomial infection, and lower cost). Performing surgery on both eyes in one session has one additional advantage which has not yet been described in the literature (according to the information available to authors). It allows surgeons to distinguish the effect of minor differences in the surgical protocol on the subjective perception of the procedure more accurately, which is a more suitable method than comparing two independent groups of patients. Purpose. To compare the effect of minor changes in the surgical protocol during SBCS on intraindividual subjective perception of surgery (pain, pressure, glare, and perception of the duration of the surgery). Methods. During the surgery of the right and left eyes of one patient, we randomly changed one surgical parameter (use of intracameral anesthesia, light intensity of the operating microscope, type of eyelid speculum, creation of the posterior circular capsulorhexis, and communication with the patient during surgery). Patients immediately after both surgeries subjectively evaluated the perception of pain (on the scale 0–10), pressure, and glare (on the scale 0–5) and estimated the duration of the surgery, separately for each eye. Each change was evaluated in a group of 50 patients. Results. In the control group with no parameters changed, we noted no difference in subjective perception of the first and second surgery. In subgroups, where we changed the protocol, we detected only minor differences in subjective perception of pain, pressure, glare, and duration of the surgery. Only one statistically significant difference in subjective pain perception was in the subgroup where we used eye intracameral anesthesia (0.34 eyes with intracameral anesthesia, 0.44 eyes with only topical anesthesia). We did not note any statistically significant differences in the perception of the time of surgery. Conclusion. SBCS can be used to optimize the parameters of cataract surgery. In our study, we noted a positive effect of intracameral anesthesia on subjective perception of surgery.
