“…The use of phaco tips as a measurement device provides a physical way to gauge groove depths and can be utilized by both established and trainee cataract surgeons. Previous texts have recommended grooves of anywhere between 2 and 4 phaco tip depths, 4 – 6 giving potential groove depths of approximately 2 mm to 4 mm but knowing that cataract lens thickness will vary between individuals (one study showing thickness variations of 4.26±0.55 mm), 9 these current recommendations may not be ideal.…”

“…The literature differs in the estimates of how many phaco tips should fit vertically inside a groove, ranging from 2–4. 4 – 6 Other visual cues include observing the red reflex, with brightening red reflex suggesting thinning posterior plate; 4 – 6 as well as observing for groove floor linear striations parallel to trench long axis, meeting at posterior Y-suture. 7 Visual techniques include utilizing good stereopsis, with better depth perception at lower magnifications.…”

AimTo describe a useful technique utilizing lens thickness from biometric data as well as phacoemulsification (phaco) probe tip dimensions, in order to more accurately determine safe groove depth during divide and conquer techniques for cataract surgery.MethodsSingle center, selection of patients for cataract surgery deemed low risk and suitable for surgical teaching cases. Individual lens thickness measurements from biometry were calculated with known phaco tip dimensions to give an individualized safe number of phaco tip depths for grooving during divide and conquer. This technique was then applied during cataract surgery.ResultsUtilization of this technique allows calculation and determination of an appropriate number of phaco tip depths of grooving for each individual patient. This technique was applied as a teaching tool for surgical trainees, with subsequent successful safe cataract surgeries completed. No posterior capsule ruptures were noted for these cases.ConclusionBy combining the biometric measurements of an individual patient’s lens thickness together with known phaco tip dimensions, individualized safe groove depths can be theoretically determined and applied during divide and conquer cataract surgery.

This prospective comparative study included 300 matched patients of different grades of senile cataract. All of them willfully underwent phacoemulsification at the hands of a single experienced surgeon, performing with a single and individual technique {Woodcutter's technique 1 }; half of them were implanted with a foldable intraocular lens and the other half with a non-foldable PMMA intraocular lens. All the patients undergoing phacoemulsification had an improvement in vision. There was no statistically significant difference in the surgically induced astigmatism after implanting foldable or non-foldable IOL.

Cataract surgery has evolved over the past few decades with progressive decrease in the size of the incision. Originally from 12 mm intracapsular incision to bimanual phacoemulsification (Micro-Phaco) that has incision size of just 700 microns. In the present comparative PROSPECTIVE study best corrected visual acuity postoperatively and surgically induced astigmatism were compared in routine Phacoemulsification technique and bimanual phaco (Micro-Phaco) 60 eyes were studied. There was no statistically significant difference in postoperative best corrected visual acuity (BCVA) of patients operated with Micro-Phaco or routine Phacoemulsification. There was difference in surgically induced astigmatism (SIA); average SIA in microphaco was 0.5972 as against 0.8328 in routine Phacoemulsification.
