Visual outcome with +10 diopter sphere correction after intracapsular cataract extraction
1Department of Ophthalmology, Faculty of Medicine, Bayero University, Kano, Nigeria.
Summary
Cataract surgery using +10 diopter sphere (DS) aphakic correction significantly restored vision in patients, particularly those who were previously blind. Priority should be given to blind patients for improved visual outcomes.
Area of Science:
- Ophthalmology
- Surgical Outcomes
- Vision Restoration
Background:
- Cataract blindness significantly impacts patient vision.
- Restoring vision post-surgery is a primary goal in ophthalmology.
- Aphakic correction plays a role in visual rehabilitation.
Purpose of the Study:
- To determine the proportion of cataract surgeries performed on blind patients.
- To evaluate the visual outcomes following +10 diopter sphere (DS) aphakic correction.
- To analyze surgical outcomes over two consecutive years (1995-1996).
Main Methods:
- Proportionate simple random sampling of cataract operations from 1995-1996.
- Analysis of 118 patient records from 1995 and 100 from 1996.
- Exclusion of 32 records due to incompleteness.
Main Results:
- Age-related cataracts were prevalent in patients aged 40-80.
- Intracapsular cataract extraction (ICCE) without intraocular lens implantation was performed.
- Vision restoration occurred in 75% (1995) and 76% (1996) of patients.
- Proportion of surgeries on blind patients was 31% (1995) and 42% (1996).
- 2% of patients remained blind post-surgery in both years.
- Statistically significant improvement in vision status after ICCE with +10 DS correction (p < 0.05).
Conclusions:
- Intracapsular cataract extraction with +10 DS correction effectively improves vision.
- Prioritizing surgeries for blind patients is crucial for maximizing visual restoration.
- The study highlights the importance of aphakic correction in cataract surgery outcomes.
