Summary
This study highlights a successful trifocal intraocular lens (IOL) implant in a patient with a prior history of small incision lenticule extraction (SMILE) for high myopia. Novel IOL power calculation methods improved visual outcomes in this complex case.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Intraocular Lens Technology
Background:
- Small incision lenticule extraction (SMILE) is a popular refractive surgery for high myopia.
- Cataract development post-refractive surgery presents unique challenges for intraocular lens (IOL) power calculation.
- Achieving spectacle independence after prior refractive surgery is a key patient goal.
Observation:
- A 54-year-old patient with a history of bilateral SMILE for high myopia developed cataracts.
- Post-SMILE aberrations were minimal, making the patient a candidate for trifocal IOL implantation.
- Standard IOL calculation methods were compared against a novel telecentric keratometry and swept-source OCT-based approach.
Findings:
- The IOL power predicted by the novel combined telecentric keratometry and swept-source OCT method was selected for implantation.
- One month post-operatively, the patient achieved excellent uncorrected distance visual acuity (UDVA) of 20/20p and near vision of N.6.
- The results suggest the superiority of newer IOL formulas in achieving satisfactory outcomes for post-refractive surgery patients.
Implications:
- Advanced IOL calculation formulas can optimize visual outcomes in patients with prior refractive surgery.
- Trifocal IOLs are a viable option for spectacle independence in carefully selected post-SMILE patients.
- This case underscores the importance of tailored refractive correction strategies in complex ophthalmic cases.

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

02:11Reporter Genes
13.0K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.

Documentation is the systematic process of formally recording, maintaining, and communicating information.
Nursing documentation records essential information and details regarding a patient's care and treatment in written or electronic form. It is a critical aspect of nursing practice that involves documenting assessments, interventions, outcomes, and other relevant details about a patient's health status.
