Phacoemulsification Techniques and Their Effects on Corneal Endothelial Cells and Visual Acuity: A Review of "Direct-Chop" and "Stop-and-Chop" Approaches Under Topical Anesthesia

Phacoemulsification is a widely adopted technique in cataract surgery that offers a minimally invasive approach to lens removal and intraocular lens implantation. Among the various methods of phacoemulsification, "direct-chop" and "stop-and-chop" techniques are particularly notable for their efficiency and safety profiles. This review aims to evaluate the effects of these two techniques on corneal endothelial cells and visual acuity, specifically under topical anesthesia. Cataract surgery outcomes hinge on the preservation of corneal endothelial cells and the achievement of optimal visual acuity. Endothelial cell loss can lead to corneal decompensation, while visual acuity is a primary measure of surgical success. The "direct-chop" technique involves the immediate chopping of the lens nucleus after groove creation, reducing phacoemulsification time and energy. Conversely, the "stop-and-chop" technique incorporates a central groove before chopping, offering increased control and safety. This review synthesizes current research and clinical studies to compare these techniques, focusing on their respective impacts on endothelial cell count and postoperative visual acuity. It examines the advantages and disadvantages of each approach, considers the role of surgeon experience, phacoemulsification energy, and anterior chamber stability, and assesses patient outcomes under topical anesthesia. The findings aim to provide insights that can guide surgeons in selecting the most appropriate technique for their patients, ultimately enhancing surgical outcomes by ensuring the preservation of corneal health and the achievement of superior visual acuity.

Assessment of Ophthalmology Teaching and its Impact on the Choice of Future Specialties Among Medical Students of Jazan University

BACKGROUND

Ophthalmology is essential for primary and specialty care physicians, as eye complaints are common, accounting for a sizable proportion of general practice consultations and emergency department visits. Fundamental ophthalmology knowledge is also relevant to other specialty fields. Thus, medical schools must provide effective undergraduate curricula to teach students about salient points, visual examination skills, emergency recognition, and referral indications. The International Council of Ophthalmology (ICO) has set guidelines that medical students should imbibe to become proficient in ophthalmology. However, there have been no recent investigations evaluating undergraduate ophthalmology education at Jazan University's Faculty of Medicine. Therefore, this study aimed to compare the curriculum at Jazan University to the ICO's requirements for undergraduate medical education.

METHODS

An observational cross-sectional study was conducted with both male and female student participants enrolled in an ophthalmology course at Jazan University's Faculty of Medicine. Following IRB approval, the questionnaire was distributed on social media to assess if Jazan University's undergraduate ophthalmology curriculum complies with ICO standards.

RESULTS

The study included a diverse sample of 322 participants, predominantly consisting of female students (n=178, 55.3%). The participants' ages ranged from 22 to 36 years, with the majority falling within the 24-25 year age range (n=173, 53.7%). Regarding academic performance, (n=117, 36.3%) of participants had a GPA of less than 4, while 66 (20.5%) had a GPA between 4.76 and 5.00. Among the respondents, 31 (9.6%) indicated having no exposure to ophthalmology, while 117 (36.3%) felt they had insufficient exposure. A considerable percentage of participants expressed competence in various areas, such as obtaining ocular history (n=113, 35.1%), testing visual acuity (n=201, 62.4%), and examining extraocular motility (n=201, 62.4%). In total, 98 participants (30.4%) expressed an interest in ophthalmology, while the majority (n=224, 69.6%) were not interested.

CONCLUSION

Essential improvements include increasing hands-on clinical experience, small-group learning, exposure across academic years, and early mentorship. Developing competency-based curricula aligned with ICO guidelines could significantly strengthen education. Better training quality and exposure will equip students with the necessary skills, boost confidence, and potentially expand the ophthalmology workforce.

Should Multifocal Intraocular Lenses Become a Standard in Phacoemulsification Cataract Surgery?

Cataracts impair daily activities such as reading, outdoor sports, and driving, which may not match best-corrected visual acuity at optimal room light conditions, but can be just as important to patients [...].
