Nanosecond Laser Cataract Surgery in LOCS III Grade 4 and 5: A Case Series
摘要： Purpose: a major obstacle to the widespread implementation of nanosecond laser cataract removal has been its limited efficacy in cases when the cataract is harder than lens opacities classification system iii (locs iii) grade 3. the latest technological modifications seem to have overcome this obstacle. Design: a case series. Methods: this study presents a case series of 17 consecutive patients with a cataract classified as harder than locs iii grade 3 who underwent nanolaser cataract surgery. the basic surgical procedure included administration of topical or local anesthesia, capsulorhexis, hydrodissection, cataract removal with a nanosecond laser, cortical cleanup, intraocular lens implantation, and clear corneal incision closure with physiological solution. Results: the nanosecond laser system effectively removed the cataract in all patients. this result was statistically significant (P < 0.000001) compared with an expected conversion rate to ultrasound phacoemulsification of 100%. Conclusions: Harder cataracts should no longer be considered a limitation for the use of nanosecond laser in cataract surgery.

Femtosecond Laser-Assisted Cataract Surgery, Technology, Outcome, Future Directions and Modern Applications
摘要： Since its introduction in 2009, femtosecond laser?assisted cataract surgery (FLACS) has promised to revolutionize cataract surgery. Despite its promise, the assessment of FLACS’s perceived benefits has proven to be far more complicated than initially might have been thought. Most studies to date have not provided validation of FLACS technology as a clinically significant advancement on our current techniques. We review FLACS technology and outcomes, including detailed analysis of safety, efficacy, cost?effectiveness, and future prospects using data from the literature and our own published clinical experience.

Phacoemulsification with coexisting corneal opacities
摘要： The treatment of choice for cases of corneal opacity with significant cataract is often a triple procedure. However, in certain situations the chances of graft survival are poor, for example in cases with deep vascularization, secondary glaucoma, and healed viral keratitis. Under these circumstances, performing cataract surgery only might improve the visual acuity enough to maintain the patient’s day-to-day activities. Performing cataract surgery, especially phacoemulsification, in these cases is challenging. Proper case selection, choosing the right technique, and a thorough idea about the difficulties and methods of tackling such cases is paramount to achieving optimum visual outcomes. In this review, we discuss the case selection and surgical modifications of performing phacoemulsification in cases with coexisting corneal opacities.

Phacoemulsification without preoperative mydriasis in patients with age-related cataract associated with type 2 diabetes
摘要： Aim: To study the effect of intracameral injection of preservative-free lignocaine to induce pupil dilatation, without using any preoperative dilating eyedrops or intraoperative mydriatics in patients with age-related cataract associated with type 2 diabetes mellitus. Design: This was a prospective, observational, and interventional case series conducted at a tertiary eyecare center in rural India. Materials and methods: A total of 32 patients underwent phacoemulsification under topical anesthesia for visually significant cataract. Preoperative pupillary diameter was measured 3 days prior to surgical procedure under mydriatics (tropicamide 0.8%, phenylephrine hydrochloride 5%). Intraoperative pupillary dilatation was achieved by 1% intracameral lignocaine solution alone. Effective phacoemulsification time (EPT), total surgical time, and final pupillary diameter were recorded at the conclusion of surgery. Results: The average duration of diabetes was 11.2 (range 5–25) years. There was no difference in dilatation by preoperative pupil-dilating drops (5.2±0.5 mm, range 3–8.3 mm) and intracameral 1% lignocaine during the surgical procedure (P=0.63). There was a negative correlation (r=-0.92) between diabetes duration and dilatation of pupils with dilating drops and intracameral lignocaine. The duration of the surgery, EPT, and phacoemulsification chop had statistically insignificant effects on mydriasis, while the grade of the nucleus had a statistically significant effect on mydriasis. Intracameral lignocaine had no significant effect on blood pressure or pulse. There were no surgical complications that could have compromised the visual outcome. None of the patients developed macular edema in a follow-up period of 3 months; 28 patients (87.5%) had best-corrected visual acuity from 20/30 to 20/20. Conclusion: Intracameral lignocaine 1% provides sufficient mydriasis for the safe phacoemulsification of cataract in patients with type 2 diabetes of variable duration.
