Purpose:To compare the safety and the visual outcomes of two experienced cataract surgeons who converted from extracapsular cataract extraction (ECCE) to manual small incision cataract surgery (MSICS) during a campaign for the prevention of blindness.Methods:Two surgeons used the ECCE technique (ECCE group) during a campaign in Burkina Faso on 93 consecutive cataract patients with a corrected distance visual acuity (CDVA) <20/80 in the best eye. Both surgeons used MSICS for the first time on 98 consecutive cases in another campaign in Kenya after theoretical instructional courses.Results:There were no significant differences in CDVA at 3 months postoperatively. There were 69% of eyes with uncorrected distance visual acuity ≥20/60 in the MSICS group and 49% eyes in the ECCE group. Spherical equivalents ranged between −1D and +1D in 55% of the MSICS group versus 43% in the ECCE group. There were significant differences in the changes in the vertical component of astigmatism (J45) but not the horizontal (J0) component. There were no significant differences in the intraoperative complications. The most common postoperative complication was corneal edema on the first day in 40.86% and 19.38% of the ECCE and MSICS groups, respectively.Conclusion:Transitioning from ECCE to MSICS for experienced cataract surgeons in surgical campaigns is safe. The rate of complications is similar for both techniques. Slightly better visual and refractive outcomes can be achieved due to the decreased induction of corneal astigmatism.

“…The issue of overnight wear versus daily wear of contact lenses for aphakia has been given substantial consideration, including patient experience and risk of complications, as many patients are elderly and face challenges with daily lens insertion, removal, and care. Overnight wear was considered to give the best experience for aphakic patients using both rigid [606,636,638,[663][664][665] and silicone elastomer lenses [666]. However, there was a high risk of problems and adverse events including MK and vision loss [636,638,663,665].…”

However, there was a high risk of problems and adverse events including MK and vision loss [636,638,663,665]. Low numbers of complications were found in daily wear aphakic rigid corneal lens wearers, which included corneal punctate staining and contact lens-papillary conjunctivitis [631,632].…”

The medical use of contact lenses is a solution for many complex ocular conditions, including high refractive error, irregular astigmatism, primary and secondary corneal ectasia, disfiguring disease, and ocular surface disease. The development of highly oxygen permeable soft and rigid materials has extended the suitability of contact lenses for such applications. There is consistent evidence that bandage soft contact lenses, particularly silicone hydrogel lenses, improve epithelial healing and reduce pain in persistent epithelial defects, after trauma or surgery, and in corneal dystrophies. Drug delivery applications of contact lens hold promise for improving topical therapy. Modern scleral lens practice has achieved great success for both visual rehabilitation and therapeutic applications, including those requiring retention of a tear reservoir or protection from an adverse environment. This report offers a practical and relevant summary of the current evidence for the medical use of contact lenses for all eye care professionals including optometrists, ophthalmologists, opticians, and orthoptists. Topics covered include indications for use in both acute and chronic conditions, lens selection, patient selection, wear and care regimens, and recommended aftercare schedules. Prevention, presentation, and management of complications of medical use are reviewed.
