Trifocal versus Extended Depth of Focus (EDOF) Intraocular Lenses After Cataract Extraction Cataract extraction surgery involves removing the clouded natural lens of the eye and replacing it with an artificial intraocular lens (IOL). Two common types of IOLs used in cataract surgery are trifocal and EDOF lenses. Trifocal IOLs * Pros: * Provide clear vision at three different distances: near, intermediate, and far * Minimize the need for glasses or contact lenses * Improve quality of life for patients who want good vision at all distances * Cons: * Can cause glare and halos around lights * May require more adjustment time for adaptation * May not be suitable for patients with certain eye conditions, such as macular degeneration or glaucoma EDOF IOLs * Pros: * Provide a wider range of clear vision than monofocal IOLs * Reduce the need for reading glasses for most activities * Preserve most of the patient’s natural depth of field * Less likely to cause glare or halos * Cons: * May not provide as good near vision as trifocal IOLs * May have some blurring at intermediate or far distances * May not be suitable for patients who want excellent vision at all distances Comparison The choice between trifocal and EDOF IOLs depends on the patient’s individual needs and preferences. * Patients who prioritize excellent vision at all distances without the need for glasses may prefer trifocal IOLs. * Patients who are more concerned about minimizing visual disturbances and want a wider range of clear vision without complete elimination of reading glasses may prefer EDOF IOLs. Other Considerations * Patient age: Trifocal IOLs are typically recommended for patients under the age of 60, as these patients have better accommodation ability. * Pupil size: Patients with larger pupils may experience more glare with trifocal IOLs. * Lifestyle: Patients who engage in activities that require good depth perception, such as driving or sports, may prefer EDOF IOLs. Ultimately, the decision between trifocal and EDOF IOLs should be made in consultation with an experienced ophthalmologist who can evaluate the patient’s specific needs and provide personalized advice.AbstractAbstract Background: Cataract is a major cause of blindness worldwide. Treatment options include eyeglasses and surgery. Intraocular lenses (IOLs) can be implanted during surgery to correct vision at different distances. Goals: To compare visual outcomes after trifocal IOLs (designed for clear vision at near, intermediate, and far distances) with extended depth of focus (EDOF) IOLs (providing clear vision over a broader range of distances). Methods: Studies comparing trifocal and EDOF IOLs in adults undergoing cataract surgery were included. Results: – Five studies were included, comparing three trifocal lenses (AcrySof IQ PanOptix, ATLISA Tri 839MP, FineVision Micro F) and one EDOF lens (TECNIS Symfony ZXR00). – Uncorrected distance visual acuity was similar between trifocal and EDOF lenses. – Trifocal lenses resulted in better uncorrected near visual acuity. – Patient-reported spectacle independence was similar for both lens types. – Patient-reported visual function scores were positive for both lens types, with no significant differences. – Surgical complications were rare and similar for both lens types. Conclusions: Distance visual acuity may be similar after cataract surgery with trifocal or EDOF IOLs. Trifocal IOLs may provide better near vision and reduce dependence on glasses. Both lenses may cause adverse visual phenomena such as glare and halos.Trifocal versus Extended Depth of Focus (EDOF) Intraocular Lenses after Cataract Extraction Patients undergoing cataract extraction face the choice between trifocal and extended depth of focus (EDOF) intraocular lenses (IOLs). While trifocal IOLs provide good vision at near, intermediate, and far distances, EDOF IOLs offer a wider range of clear vision without the need for bifocals or reading glasses. A recent study compared the outcomes of trifocal and EDOF IOLs in patients after cataract extraction. The study found that both types of IOLs provided good quality of vision. However, trifocal IOLs provided better near vision and intermediate vision, while EDOF IOLs offered better distance vision. Another study found that patients with trifocal IOLs had a higher incidence of visual disturbances, such as glare and halos, compared to patients with EDOF IOLs. However, the visual disturbances were typically mild and did not interfere with daily activities. The choice between trifocal and EDOF IOLs depends on individual patient preferences and lifestyle. Patients who value excellent near vision and intermediate vision may prefer trifocal IOLs. Patients who prioritize distance vision and minimize visual disturbances may prefer EDOF IOLs. In conclusion, both trifocal and EDOF IOLs offer good quality of vision after cataract extraction. The best choice for each patient depends on their individual needs and preferences.
