Congenital cataracts can be associated with other ocular developmental abnormalities, including microphthalmia, microcornea, or aniridia and with systemic findings. Next-generation sequencing (NGS) and forthcoming new ultra-high-throughput sequencing represent excellent tools to investigate the genetic causes of congenital cataracts. A better recognition of different clinical presentations and underlying etiologies of congenital cataracts may lead to the development of new approaches to improve visual outcome after cataract surgery and promote early detection of systemic associated syndromes.The crystalline lens is an important optic element in human eyes. It is transparent and biconvex, refracting light and accommodating to form a clear retinal image. The lens originates from the embryonic ectoderm. The epithelial cells at the lens equator proliferate, elongate and differentiate into highly aligned lens fiber cells, which are the structural basis for maintaining the transparency of the lens. Cataract refers to the opacity of the lens. Currently, the treatment of cataract is to remove the opaque lens and implant an intraocular lens (IOL). This strategy is inappropriate for children younger than 2 years, because a developing eyeball is prone to have severe complications such as inflammatory proliferation and secondary glaucoma. On the other hand, the absence of the crystalline lens greatly affects visual function rehabilitation. selleck compound The researchers found that mammalian lenses possess regenerative potential. We identified lens stem cells through linear tracking experiments and designed a minimally invatrong self-renewal and repair ability.
To determine whether patients with severe vision impairment due to advanced age-related macular degeneration (AMD) benefit from bilateral cataract surgery in terms of vision-related quality of life (QoL).

A prospective interventional single-center study. Ten patients with severe vision impairment due to advanced bilateral AMD were included. The preoperative corrected distance visual acuity (CDVA) was ≥1.0/≥1.0 LogMAR units on Snellen chart and <20/<20 points on Early Treatment Diabetic Retinopathy Study (ETDRS) chart. Patients were not on active treatment for wet AMD as the treatment was expected to have no effect or benefit. The patients were scheduled for immediate sequential bilateral cataract surgery, with target refraction emmetropia (SN60WF, Alcon). Vision-related QoL was measured with National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) preoperatively, at 3 months and 1 year.

The mean age of the patients was 82.5±6.2 years. The mean NEI VFQ-25 overall composite score changed from 44.0±7.1 preoperatively to 54.9±13.7 at 3 months and to 56.9±15.6 at 1 year (P=0.045, Friedman test). During the 1-year follow-up, there was an improvement in the subscale scores indicating difficulty with peripheral vision, mental health symptoms, and role difficulties due to vision (P<0.05 for all, Wilcoxon sign-rank test).

Cataract surgery may improve the vision-related QoL in patients with severe vision impairment due to bilateral advanced AMD.

Although influencing the severity of postoperative intraocular inflammation of congenital cataract, the developmental characteristics of cytokine profile in the aqueous humor during childhood had not been described. And its relationship with the inflammatory response after intraocular surgery remained unsolved.

Preoperative aqueous humor samples were collected from 65 eyes of congenital cataract patients (CC group) and 13 eyes of age-related cataract patients (ARC group) from January 2015 to May 2017. The concentrations of 22 cytokines were measured. Differences in concentrations between the CC and ARC groups were described. Correlation analysis, least absolute shrinkage and selection operator (LASSO) and multivariate linear regression were then used to investigate the dynamic changes in the cytokine profile with age and their relationships with the postoperative inflammatory response.

The concentrations of granulocyte colony stimulating factor (G-CSF), interferon (IFN)-α2, interleukin (IL)-1α and IL-7 hese findings can serve as the foundation for further investigation into the mechanisms that underlie the early development of intraocular immunology.

To evaluate the learning-curve in performing cataract surgery with respect to developments in technology and different teaching strategies by comparing the incidence of capsular bag-related complications to operator experience.

A review of the registry of 14,520 cataract surgeries carried out at the Ophthalmology Unit of Kymenlaakso Central Hospital, Kotka, Finland, from August 8, 2009 to July 31, 2017.

We identified 144 cases with posterior capsule rupture and/or loss of capsular bag support (incidence 0.99% of all surgeries). The mean age of patients was 76.9±9.1 years and gender distribution ratio 2971 malefemale. Pseudoexfoliation syndrome (PXF; incidence 21%) and small pupil (incidence 14%) were over-represented in complication eyes, especially at the beginning of the study. Capsular bag-related complication rates were reported in 0.36% of surgeries for senior and 7.03% for resident surgeons at the beginning of the study, compared to 0.32% and 1.32%, respectively, at the end of the study. Best-corrected visual acuity at the final post-operative visit was 0.61±0.16 decimals at the beginning of the study, and 0.81±0.19 decimals at the end of the study. The mean number of post-operative visits was 4.3±2.7 and did not show trend over the study period.

Real-world evidence suggests PXF and small pupil as significant risk factors in cataract surgery. A gradual decline in the rate complications was noted with increasing surgical experience, also among residents over the follow-up period.
